PART I Introduction
Welcome to WatchGuard
The WatchGuard Firebox System consists of:
• A suite of management and security software tools
• A Plug and Play network appliance called the WatchGuard Firebox
• A security-related broadcast service
In the past, a connected enterprise needed a complex set of tools, systems, and
personnel for access control, authentication, virtual private networking, network
management, and security analysis. These costly systems were difficult to integrate
and not easy to update. Today, the WatchGuard Firebox System delivers a complete
network security solution to meet modern security challenges:
• Keep network defenses current
• Protect every office connected to the Internet
• Encrypt communications to remote offices and traveling users
• Manage the security system from a single site
The WatchGuard Firebox System is a reliable, flexible, scalable, and inexpensive
network security solution. Its setup and maintenance costs are small, and it supports
a rich feature set. When properly configured and administered, the Firebox System
reliably defends any network against external threats.
WatchGuard Firebox System components
The WatchGuard Firebox System has all of the components needed to conduct e-
business safely. It is made up of the following:
• Security appliance (the WatchGuard Firebox)
• Control Center

WatchGuard Control Center
WatchGuard Control Center is a toolkit of applications run from a single location,
enabling you to configure, manage, and monitor your network security policy.
Control Center includes:
Policy Manager
Used to design, configure, and manage the electronic portion of a network
security policy.

keywords and fields, and print and save to a separate file.
HostWatch
Displays active connections occurring on a Firebox in real time or represents
the connections listed in a log file. HostWatch either plays back a previous file
for review or displays connections in real time, as they are added to the
current log file.
Historical Reports
Creates HTML reports that display session types, most active hosts, most used
services, URLs, and other data useful in monitoring and troubleshooting your
network.
WatchGuard security suite
In addition to basic security policy configuration, the Firebox System includes a suite
of advanced software features. These include:
• User authentication

PART II WatchGuard Services
The WatchGuard Firebox System is considerably more than a piece of hardware. This
section describes two WatchGuard service components that address your security
requirements, and the optional features available to you.
LiveSecurity Service
The key to a high quality, effective network security policy is rapid response
to challenges and threats. The LiveSecurity Service enables network security
experts to provide quick responses to the changing Internet security
environment. Information such as alerts, editorials, threat responses, and
software updates are sent through your e-mail client.
Technical Support
The WatchGuard Technical Support team offers services to assist
configuration and administration of the Firebox System. Services include
Frequently Asked Questions, a WatchGuard user-group mailing list, Internet
and telephone support, and training.
WatchGuard Optional Features
WatchGuard expands its network security package with additional features
suited to some company and office environments. Current offerings include
VPN Manager, High Availability, Mobile User VPN, and SpamScreen.

CHAPTER 1
LiveSecurity Service
No Internet security solution is complete without systematic updates. From the latest
hacker techniques to the most recently discovered operating system bug, the daily
barrage of new threats poses a perpetual challenge to any Internet security solution.
The LiveSecurity Service keeps your security system up-to-date by delivering
solutions to you. Software Updates, Threat Responses, and other broadcasts are e-
mailed directly to your desktop.
LiveSecurity broadcasts
The WatchGuard LiveSecurity Rapid Response Team periodically broadcasts
information and software directly to your desktop through e-mail. Broadcasts are
divided into several channels to help you immediately recognize and process
incoming information.
Information Alert
Information Alerts provide timely notification of breaking news and current
issues in Internet security. By the time the mass media report on a new hacker
threat, you have already been briefed on its impact and the proper system
configuration necessary to protect against it.
Threat Response
After a newly discovered threat is identified, the Rapid Response Team
transmits an update specifically addressing this threat to make sure your
network is continuously protected. Each Threat Response includes a
description detailing the nature and severity of the threat, the risks it poses,
and what steps you should take.
Software Update
In addition to Threat Responses that address security challenges, you receive
functional software enhancements on an ongoing basis that cover your entire
WatchGuard Firebox System. An installation wizard and release notes

LiveSecurity broadcasts
accompany each transmission for easy installation. These convenient
transmissions relieve you of the burden of tracking the latest software version
to keep your system state of the art.
Editorial
Leading security experts from around the world join the WatchGuard Rapid
Response Team in contributing useful editorials to provide a source of
continuing education on this rapidly changing subject.
Support Flash
These technical tutorials provide tips for managing the WatchGuard Firebox
System. Support Flashes supplement other resources such as online Help,
FAQs, and Known Issues pages on the Technical Support Web site.
Virus Alert
In cooperation with TrendMicro, WatchGuard issues weekly broadcasts that
provide the latest information on new computer viruses. WatchGuard also
issues special virus-specific alerts as conditions warrant.
New from WatchGuard
To keep you abreast of new features, product upgrades, and upcoming beta
programs, WatchGuard announces their availability first to our existing
customers.

Firebox manages traffic and protects the network while the second waits in a passive,
listening mode. If the first Firebox fails for any reason, the second Firebox
immediately takes over. When the first Firebox returns to functioning capacity, the
second Firebox again takes the passive role, ensuring that your network is constantly
protected.
To use High Availability, purchase the High Availability option as well as a second
Firebox of the same model as your first.

Obtaining WatchGuard options
Mobile User VPN
Mobile User VPN is the WatchGuard IPSec implementation of remote user virtual
private networking. Mobile User VPN connects an employee on the road or working
from home to trusted and optional networks behind a Firebox using a standard
Internet connection, without compromising security.
Mobile User VPN licenses are available in packs of five. Each license enables a
connection for one remote host IP address.
SpamScreen
SpamScreen helps to control “spam”–e-mail sent to you or your end users without
permission. Spam consumes valuable bandwidth on your Internet connection and on
the hard disk space and CPU time of your mail server. If allowed to enter your
network unchecked, spam consumes workers’ time to read and remove. WatchGuard
SpamScreen identifies spam as it comes through the Firebox. You can choose to either
block the spam at the Firebox or tag it for easy identification or sorting.

PART III Configuring a Security Policy
This section describes how to configure your security system. Its primary focus is on
using the WatchGuard Control Center and Policy Manager to develop and
implement a network security policy. It includes chapters on:
WatchGuard Control Center
The WatchGuard Control Center is an intuitive management, monitoring, and
reporting package that puts everything you need at your fingertips. From a
single location, you can configure your system, implement security policies,
and monitor all of your protected systems.
Firebox basics
Complete basic tasks related to setting up and using the Firebox hardware,
including opening and saving configuration files, and setting the Firebox time
zone.
Configure a network
After installation, the next step in implementing a security policy is to
delineate your network. Set up either a drop-in or routed network, add
secondary networks, and define network and host routes.
Block sites and ports
Use default packet handling to establish a global policy for dynamically
blocking packets and sites. Alternatively, configure your network to
permanently block individual sites and ports.
Configure services
With the network configured, apply protection for individual services such as
SMTP and FTP. Define both incoming and outgoing traffic rules as well as
specific service properties.
Control Web traffic
Use the WebBlocker feature of the WatchGuard Firebox System in conjunction
with the HTTP proxy to provide Web-site filtering capabilities. This enables

you to exert fine control over the type of Web sites users on your Trusted
network are allowed to view.
Set up network address translation (NAT)
Hide the real IP addresses of the hosts and networks behind your firewall
through the use of network address translation. You can set NAT policy at
both the global and the individual service levels.
Set up logging and notification
What events are logged and how and when a network administrator is
notified is an important component of a security policy. Assign and configure
the LiveSecurity Event Processor and set both global and service-specific log
and notification preferences.
Connect with out-of-band management
Configure a Firebox over a modem connection using out-of-band (OOB)
management.

CHAPTER 4
Firebox Basics
This chapter describes the following tasks, which require direct interaction between
the Management Station and the Firebox:
• Set up a Firebox
• Open and save a configuration file to a local hard disk or the Firebox
• Reset Firebox passphrases
• Set the Firebox time zone
• Reinitialize a misconfigured Firebox
• Manage the flash memory of the Firebox
What is a Firebox?
Fireboxes are specially designed and optimized machines. They are small, efficient,
and reliable.
There are no user-serviceable parts within the Firebox. If a user
opens a Firebox case, it voids the limited hardware warranty.

Control Center.
Event Processor
The computer that receives and stores log messages and sends alerts and
notifications. You can configure the Management Station to also serve as the
Event Processor.
Trusted network
The network behind the firewall that must be protected from the security
challenge.
External network
The network presenting the security challenge, typically the Internet.
Optional network
A network protected by the firewall but still accessible from the trusted and
the external networks. Typically, the optional network is used for public
servers such as an FTP or Web server.

Opening a configuration file
Opening a configuration file
Policy Manager is a comprehensive software tool for creating, modifying, and saving
configuration files. A configuration file, with the extension .cfg, contains all the
settings, options, addresses, and information that together constitute your Firebox
security policy. You can open and edit a configuration file residing on either your
local hard disk or in the primary area of the Firebox flash disk. From Policy Manager:

Saving a configuration file
After making changes to a configuration file, you must save it to a local hard disk.
When you save a new configuration directly to a Firebox, Policy Manager prompts
you to restart that Firebox so that it will use the new configuration. The new policy is
not active until the Firebox finishes rebooting. Some tasks, such as adding new
Firebox users and changing certain IPSec settings, do not require a restart in order to
take effect.

Tips for creating secure passphrases
Although an attacker could crack any passphrase eventually, you can toughen your
passphrases using the following tips:
24
Download from Www.Somanuals.com. All Manuals Search And Download.
Setting the time zone
• Don’t use words in standard dictionaries, even if you use them backward or in
a foreign language. Create your own acronyms instead.
• Don’t use proper names, especially company names or those of famous people.
• Use a combination of uppercase and lowercase characters, numerals, and
special characters (such as Im4e@tiN9).
Setting the time zone
The Firebox time zone determines the date and time stamp that appear on logs and
that are displayed by services such as LogViewer, Historical Reports, and
WebBlocker. Use the time zone to view log information in local time. The default time
zone is Greenwich Mean Time (Coordinated Universal Time).
From Policy Manager in the Advanced view:
1
2
Select Setup => Time Zone.
Use the drop list to select a time zone. Click OK.
Check the drop list carefully. WatchGuard provides a comprehensive list of time zones to
accommodate areas in the same general time zone that follow different rules regarding the
observance and/or onset and rollback of Daylight Saving Time, and other timekeeping details.
Reinitializing a misconfigured Firebox
The Firebox can boot from the primary area of the flash disk (Sys A) in a mode that
provides fail-safe access in cases when you need to:
• Install a Firebox for the first time
• Troubleshoot problems in which all access to the Firebox is lost
• Reset Firebox passwords when you do not know or have forgotten them
This Enhanced System Mode is the default mode for new Fireboxes shipped from the
factory. If a Firebox is in this mode, its Sys A light blinks. A Firebox can also be placed
into Enhanced System Mode by connecting any two of the Firebox Ethernet interfaces
in a loopback configuration. Use a red crossover cable included with the Firebox for
this purpose.
To access a Firebox in Enhanced System Mode:
1
Establish a physical Ethernet connection between the Trusted interface of the
Firebox and the Management Station on the same segment.
2
Attach the red crossover cable between the remaining two Firebox interfaces, and
then turn the power on the Firebox off and then on. If a small, “factory default”
switch is present on the rear of the Firebox, press and hold that switch while you
turn the Firebox power off and then on.
The Firebox boots into the Enhanced System Mode. This is indicated by a blinking Sys A light.
3
Reinitialize the Firebox using the QuickSetup wizard.
For more information on the QuickSetup wizard, see the Install Guide.

• A duplication of the Firebox front panel that graphically displays traffic flow
and rejected packets
• Firebox and VPN tunnel status
User Guide
27
Download from Www.Somanuals.com. All Manuals Search And Download.
Control Center components
• A real-time monitor of traffic through the Firebox.
QuickGuide
The top part of the display just below the title bar is the QuickGuide. It contains
buttons to:
• Open the WatchGuard Control Center menu
• Pause the display
• Launch Policy Manager
• Launch Firebox Monitors
• Launch LogViewer
• Create Historical Reports
• Change the dimensions of the Firebox and Tunnel Status window
Front panel
Under the toolbar is a representation of the front panel of the Firebox, including the
Security Triangle Display, Traffic Volume Indicator, Processor Load Indicator, and
basic status information.
The lights on the display represent those found on the front panel of the Firebox. The
triangle shows the predominant flows of traffic among the Trusted, External, and
Optional interfaces. A red corner of the triangle lights when that interface is blocking
packets. The two bar graphs indicate traffic volume and the proportion of Firebox
capacity being used.
Firebox and VPN tunnel status
The section in the Control Center directly below the front panel shows the current
status of the Firebox and of Branch Office VPN tunnels and Remote VPN tunnels.
Firebox status
In Firebox status, three branches show the traffic being sent and received through the
three Firebox interfaces – Trusted, External, and Optional. Specifically, the status
box provides the MAC (network Ethernet card) address of each interface, and the
number of packets sent and received since the last time the Firebox rebooted.
High Availability host
If the High Availability option is installed, the first entry within the Firebox Status
tree is High Availability host. When properly configured and operational, the IP
address of the standby box appears. If High Availability is installed but the secondary
Firebox is not responding, the display indicates “Not Responding.”
Branch office VPN tunnels
Beneath Firebox status is a branch for branch office VPN tunnels, in which three
categories of branch office VPN tunnels appear:
28
Download from Www.Somanuals.com. All Manuals Search And Download.
Control Center components
• IPSec
• DVCP
• WatchGuard VPN
The first line of the tunnel entry shows the name that was assigned when the tunnel
was created, along with the tunnel type (IPSec, DVCP, or WatchGuard). If the tunnel
is an IPSec or DVCP tunnel, it also shows the IP address of the destination IPSec
device (such as another Firebox, SOHO, or SOHO|tc). If the tunnel is DVCP, the IP
address refers to the entire remote network address rather than that of the Firebox or
equivalent IPSec device.
The next two lines display the amount of data sent and received on that tunnel in
both bytes and packets.
If the tunnel is IPSec or DVCP, the lines below the packet quantities show when the
key expires and the tunnel is renegotiated. Expiration can be expressed in bytes
passed or time deadline. DVCP tunnels that have been configured for both traffic and
time deadline expiration thresholds display both; this type of tunnel expires when
either event occurs first (time runs out or bytes are passed). These lines below the
packet quantities also show the authentication and encryption levels set for that
tunnel.
If the tunnel is using WatchGuard VPN, the tunnel displays the packet statistics only.
Remote VPN tunnels
Following the branch office VPN tunnels is an entry for remote VPN tunnels. Remote
VPN tunnels can either be Mobile User VPN (with IPSec) or Remote User PPTP.
If the tunnel is Mobile User VPN, the branch displays the same statistics as for the
DVCP or IPSec Branch Office VPN as described previously. The tunnel shows the
tunnel name, followed by the destination IP address, followed by the tunnel type.
Below are the packet statistics, followed by the key expiration, authentication, and
encryption specifications.
If the remote VPN tunnel is PPTP, then the display shows only the quantity of sent
and received packets. Byte count and total byte count are not applicable to PPTP
tunnel types.
Expanding and collapsing the display
To expand a branch of the display, click the plus sign (+) next to the entry, or double-
click the name of the entry. To collapse a branch, click the minus sign (—) next to the
entry. A lack of either a plus or minus sign indicates that there is no further
information about the entry.
Red exclamation point
A red exclamation point appearing next to any item indicates that something within
its branch is not functioning properly. For example, a red exclamation point next to
the Firebox entry indicates that a Firebox is not communicating with either the
LiveSecurity Event Processor or Management Station. A red exclamation point next
to a tunnel listing indicates a tunnel is down.

Working with the Control Center
When you expand an entry that has a red exclamation point, another exclamation
point appears next to the specific device or tunnel with the problem. Use this feature
to rapidly identify and locate problems with your VPN network.
Traffic Monitor
The Traffic Monitor shows, in real time, the traffic through the Firebox.
Working with the Control Center
The basic tasks you perform with the Control Center are connecting to a Firebox,
changing the interval at which the Firebox is queried for status information, and
opening other Firebox System applications. You can also move and work with the
Traffic Monitor display to best suit your needs.

CHAPTER 6
Configuring a Network
Configuring a network refers to setting up the three Firebox interfaces. To do this,
you need to:
• Enter the IP address or addresses for the Firebox interfaces.
• Enter the IP addresses of secondary networks that are connected to and
associated with a Firebox interface.
• Enter the default gateway for the Firebox.
Use Policy Manager to configure parameters for the three Firebox interfaces–
Trusted, External, and Optional.
Trusted
Modify settings for the Ethernet device connecting the Firebox to the
protected LAN or other host.
External
Modify settings for the Ethernet device connecting the Firebox to the outside
world.
Optional
Modify settings for the Ethernet device connecting the Firebox to the optional
bastion network (this is sometimes called the “Demilitarized Zone,” or
“DMZ”). As its name implies, you can use the Optional network in different
ways. One common application is to use it for a public Web server.
Running the QuickSetup wizard
During the installation of the WatchGuard Firebox System, you are prompted to run
the QuickSetup wizard. The QuickSetup wizard creates a basic configuration file and
saves it to the primary area (Sys A) of the Firebox flash disk. The Firebox loads the
primary configuration file when it boots.
User Guide
35
Download from Www.Somanuals.com. All Manuals Search And Download.
Setting up a drop-in network
The QuickSetup wizard also writes a basic configuration file called
wizard.cfg to the hard disk of the Management Station. If you later want to expand
or change the basic Firebox configuration using Policy Manager, use wizard.cfg as
the base file to which you make changes.
You can run the QuickSetup wizard again at any time to a create new, basic
configuration file.
The QuickSetup wizard replaces the configuration file, writing over any prior
version. To make a backup copy of the configuration file on the flash disk, see
the Firebox System Area chapter in the Reference Guide
.
To run the QuickSetup wizard:
1
Complete the Network Configuration Worksheet.
A copy is included with the Install Guide. It can also be found as a .pdf file in the WatchGuard
Documentation directory.
2
From the Windows Desktop, select S t a r t => P r o g r a m s => Wa t c h G u a r d =>
QuickSetup Wizard.
You can also, from the Control Center, select LiveSecurity => QuickSetup Wizard. The
QuickSetup wizard prompts for information about your network and security policy preferences.
Documentation for running the QuickSetup wizard is contained in the
wizard’s on-panel instructions, Install Guide, and Online Help.
When the wizard prompts you to enter monitoring (read-only) and
configuration (read-write) passphrases, use two completely different
passphrases.
Setting up a drop-in network
A drop-in network configuration is useful for situations where you can distribute
network address space across the Firebox interfaces. In a drop-in configuration, you
place the Firebox physically between the router and the LAN, without reconfiguring
any of the machines on the Trusted interface.
Characteristics of a drop-in configuration:
• A single network that is not subdivided into smaller networks; the network is
not subnetted.
• WatchGuard performs proxy ARP.
- The Firebox answers ARP requests for machines that cannot hear the
broadcasts.
- The Firebox can be placed in a network without changing default gateways
on the Trusted hosts. This is because the Firebox answers for the router, even
though the router cannot hear the Trusted host’s ARP requests.
- To enable proxy ARP, you must assign the same IP address to all three
interfaces for the Firebox. This is the only supported address assignment in
drop-in configuration.
• All Trusted computers must have their ARP caches flushed.
36
Download from Www.Somanuals.com. All Manuals Search And Download.
Setting up a routed network
• The Trusted interface ARP address replaces the router’s ARP address.
• All three Firebox interfaces are assigned the same IP address. This is true
whether or not you use the Optional interface.
• The majority of a LAN resides on the Trusted interface.
• You can have other networks in other address ranges behind the Firebox using
secondary networks. List the IP address of secondary networks in the
configuration file.
Use the sample network configuration and the Network Configuration Worksheet
(found in the Install Guide) to design your drop-in network. Then either run the
QuickSetup wizard to create a new configuration file or manually modify an existing
configuration file using Policy Manager. To set up a drop-in network, from Policy
Manager:
1
2
Select Network =>Configuration. Click the Drop-In Configuration tab.
Enable the Automatic checkbox if you want the Firebox to use proxy ARP for all
hosts. Disable the checkbox if you want the Firebox to use proxy ARP only on
behalf of all hists on the network you specify with the Default Network drop-
down menu.
When automatic mode is enabled, the Hosts list is useful to lock a host to the specified interface.
To add specific hosts that the Firebox should use proxy ARP for, enter the IP address and the
interface they reside on in the Hosts section of the Drop-In Configuration tab.
3
4
Click Add to add a new host. To remove a host, select it and click Remove.
When you are done setting up your network, click OK.
Setting up a routed network
Use a routed network configuration when the Firebox is put in place with separate
logical networks on its interfaces. This configuration assigns separate network
addresses to at least two of the three Firebox interfaces.
If you have two separate network addresses and you want to use the routed
configuration, use only the External and Trusted interfaces (not the Optional
interface). Each interface must be on a separate network in routed configuration
mode.
If you have three or more network addresses, use the routed network configuration
and map a network to each interface. Add more networks as secondary networks to
one of the interfaces. You can relate different networks to different interfaces. Those
networks then come under the protection and access rules set up for that interface.
The Firebox forwards packets to the various interfaces depending on how you define
and configure services in Policy Manager.

Adding a secondary network
Adding a secondary network
A secondary network is a network on the same physical wire as a Firebox interface
that has an address belonging to an entirely different network. Adding a secondary
network to a Firebox interface maps an IP address from the secondary network to the
IP address of the interface. This process is also known as adding an IP alias to the
Firebox interface.
The secondary network IP address becomes the default gateway for all the machines
on that network. Adding the secondary network also tells the Firebox that another
network resides on the wire.
The Policy Manager does not verify that you have entered the correct address.
Check secondary network addresses carefully. For example, WatchGuard
recommends that you not enter a subnet on one interface that is part of a
larger network on another interface.
The procedure for adding a network route to all three of the Firebox interfaces is
identical. The description below is for a secondary network on the Optional interface.

Entering WINS and DNS server addresses
Entering WINS and DNS server addresses
Several advanced features of the Firebox, such as DHCP and Remote User VPN, rely
on shared Windows Internet Name Server (WINS) and Domain Name System (DNS)
server addresses. These servers must be accessible from the Firebox Trusted interface.

Select Network =>Configuration. Click the General tab.
Enter primary and secondary addresses for the WINS and DNS servers. Enter a
domain name for the DNS server.
Defining a Firebox as a DHCP server
Dynamic Host Configuration Protocol (DHCP) is an Internet protocol that simplifies
the task of administering a large network. A device defined as a DHCP server
automatically assigns IP addresses to network computers from a defined pool of
numbers. You can now define the Firebox as a DHCP server for your network behind
the firewall.
One parameter that you define for a DHCP server is lease times. This is the amount of
time a DHCP client can use an IP address that it received from the DHCP server.
When the time is close to expiring, the client will contact the DHCP server to renew
the lease.
From Policy Manager:
1
2
3
Select Network =>Configuration. Click the DHCP Server tab.
Enable the Enable DHCP Server checkbox.
Enter the default lease time for the server.
The default lease time is provided to clients who don’t specifically request times.
4
Enter the maximum lease time.
The maximum lease time is the longest time the server will provide for a client. If a client
requests a longer time, the request is denied and the maximum lease time is provided.
Adding a new subnet
To increase the number of available (private) IP addresses available to DHCP clients,
add a subnet. To add a new subnet, you specify a range of IP addresses to be assigned
to clients on the network. For example, you could define the address range from
10.1.1.100 to 10.1.1.19. This gives clients a pool of 10 addresses. From Policy Manager:

CHAPTER 7
Blocking Sites and Ports
Many types of network security attacks are easily identified by patterns found in
packet headers. Port space probes, address space probes, and spoofing attacks all
exhibit characteristic behavior that a good firewall can recognize and protect against.
WatchGuard allows both manual and dynamic blocking of ports and sites, and uses
default packet-handling options to automatically and temporarily block hosts that
originate probes and attacks. Logging options can assist you in identifying suspect
sites that repeatedly exhibit suspicious behavior. You can then manually and
permanently block a suspect site. In addition, you can protect ports with known
vulnerabilities by blocking their unauthorized use.
Configuring default packet handling
The WatchGuard Firebox System examines and handles packets according to default
packet-handling options that you set. The firewall examines the source of the packet
and its intended destination by IP address and port number. It also watches for
patterns in successive packets that indicate unauthorized attempts to access the
network.
The default packet-handling configuration determines whether and how the firewall
handles incoming communications that appear to be attacks on a network. Packet
handling can:
• Reject potentially threatening packets
• Automatically block all communication from a source site
• Add an event to the log
• Send notification of potential security threats
From Policy Manager in the Advanced view:

Select Setup =>Default Packet Handling.

Blocking a site permanently
The WatchGuard auto-blocking and logging mechanisms help you decide which sites
to permanently block.
Use Policy Manager to block a site permanently. The default configuration blocks
three network addresses – 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. These are
the “unconnected” network addresses. Because they are for private use, backbone
routers should never pass traffic with these addresses in the source or destination
field of an IP packet. Traffic from one of these addresses is almost certainly a spoofed
or otherwise suspect address. RFCs 1918, 1627, and 1597 cover the use of these
addresses.
The Blocked Sites list applies only to traffic on the External interface.
Connections between the Trusted and Optional interfaces are not subject to
the Blocked Sites list.

On the toolbar, click the Blocked Sites icon.
You can also select Setup => Blocked Sites. The Blocked Sites dialog box appears.

Blocking a port permanently
You can block ports to explicitly cut off from external access certain network services
that are vulnerable entry points to your network. The Blocked Ports list takes
precedence over all service properties. For more information on precedence, see
Chapter 8, “Configure Services.”
Blocking ports can be useful in several ways:
• Blocked ports provide an independent check to protect the most sensitive
services. Even if another part of your security policy is misconfigured, blocked
ports provide an additional defense for the most vulnerable services.
• Probes to particularly sensitive services can be logged independently.
• Some TCP/IP services that use ports greater than 1024 are vulnerable to attack
if the attacker originates the connection from an allowed well-known service
less than 1024. Thus, these connections can be attacked by appearing to be an
allowed connection in the opposite direction. You should add the port numbers
of such services to the Blocked Ports list.
By default, Policy Manager blocks quite a few destination ports. This measure
provides convenient defaults that many administrators find sufficient. However,
additional ports can be added to the Blocked Ports list. From Policy Manager:

Setting up proxy services
The WatchGuard Firebox System uses a technology called “transparent proxies.”
Transparent proxies can be employed without any special third-party or proxy-aware
software, and are transparent to client programs. WatchGuard has application-
specific proxies for SMTP, FTP, and HTTP.
When performing incoming, static NAT, internal hosts must point to the
internal IP address of the server, not the Firebox or public IP address.
Users should have their WINS, host file, or internal DNS set to resolve to
the internal IP of the server in question. For more information, see
Configuring an SMTP proxy service
The SMTP proxy limits several potentially harmful aspects of e-mail. The proxy scans
the content type and content disposition headers and matches them against a user-
definable list of known hostile signatures. E-mail containing suspect attachments is
blocked and replaced with messages indicating that this action has been taken.
The list of disallowed signatures can be modified from the Content Types tab in the
SMTP Proxy dialog box. You do not have to reboot the Firebox when you make these
SMTP configuration changes.
The proxy also automatically disables nonstandard commands such as Debug, and
can limit message size and number of recipients. If the message exceeds preset limits,
the Firebox refuses the mail.
The Policy Manager uses separate dialog boxes for incoming and outgoing SMTP
rules. Because incoming messages pose a greater threat to your network than
outgoing ones, the dialog box for incoming SMTP has more controls and configurable
properties.

Configuring an HTTP proxy service
HyperText Transfer Protocol (HTTP) is the protocol used by the World Wide Web to
move information around the Internet. HTTP defines how messages are formatted
and transmitted, and what actions Web servers and browsers take in response to
commands. For example, when you enter a URL into your browser, you are sending
an HTTP command to the Web server, directing it to find and send you the requested
Web page.
The HTTP proxy does content-based filtering on outgoing connections only, with a
set of options that you can easily configure according to your own requirements. The
HTTP proxy does not process incoming connections. In addition, the HTTP proxy can
serve as a content filter for Web browsers. For more information, see “Configuring the
You can use two types of HTTP services:
• Proxied-HTTP service allows outbound HTTP on TCP port 80 to be proxied
through the Firebox. The proxy has the capability of performing HTTP-specific
content filtering of each connection. Such content filtering can include denying
or removing “unsafe” content types (such as Java or ActiveX) and performing
general verifications on the HTTP exchange.
• Filtered-HTTP service allows outbound HTTP on all TCP ports, but incoming
access only on port 80. Filtered HTTP is filtered by the standard packet filter,
which can restrict access by IP address or alias only. No proxy is used with this
service, meaning that Filtered-HTTP cannot make use of any of the advanced
HTTP-specific content-filtering options provided by the proxy. You must use
proxied-HTTP if you want accounting logs – for example, byte counts.
With either type of HTTP service, you should have a single icon that allows for
general outgoing HTTP access (for most internal users) and incoming HTTP access to

Service precedence
Precedence is generally given to the most specific service and descends to the most
general service. However, exceptions exist. There are three different precedence
groups for services:
• The “Any” service (see the Online Help system for information about the
“Any” packet filter service). This group has the highest precedence.
• IP and ICMP services and all TCP/UDP services that have a port number
specified. This group has the second highest precedence and is the largest of the
three.
• “Outgoing” services that do not specify a port number (they apply to any port).
This group includes Outgoing TCP, Outgoing UDP, and Proxy.
“Multiservices” can contain subservices of more than one precedence group.
“Filtered-HTTP” and “Proxied-HTTP,” for example, contain both a port-specific TCP
subservice for port 80 as well as a nonport subservice that covers all other TCP
connections. When precedence is being determined, individual subservices are given
precedence according to their group (described previously) independent of the other
subservices contained in the multiservice.
Precedence is determined by group first. Services from a higher precedence group
always have higher precedence than the services of a lower-precedence group,
regardless of their individual settings (for example, the lowest precedence “Any”
service will take precedence over the highest precedence Telnet service).
The precedences of services that are in the same precedence group are ordered from
the most specific services (based on source and destination targets) to the least
specific service. The method used to sort services is based on the specificity of targets,
from most specific to least specific. The following order is used:

“IP” refers to exactly one host IP address; “List” refers to multiple host IP addresses, a
network address, or an alias; and “Any” refers to the special “Any” target (not “Any”
services).
When two icons are representing the same service (for example, two Telnet icons or
two Any icons) they are sorted using the above tables. The most specific one will
always be checked first for a match. If a match is not made, the next specific service
will be checked, and so on, until either a match is made or there are no services left to
check. In the latter case, the packet is denied. For example, if there are two Telnet
icons, telnet_1 allowing from A to B and telnet_2 allowing from C to D, a Telnet
attempt from C to E will first check telnet_1, and then telnet_2. Because no match is
found, the rest of the rules are considered. If an Outgoing service will allow from C to
E, it will do so.
When only one icon is representing a service in a precedence category, only that
service is checked for a match. If the packet matches the service and both targets, the
service rule applies. If the packet matches the service but fails to match either target,
the packet is denied. For example, if there is one Telnet icon allowing from A to B, a
Telnet attempt from A to C will be blocked without considering any services further
down the precedence chain, including Outgoing services.

CHAPTER 9
Controlling Web Traffic
WebBlocker is a feature of the Firebox System that works in conjunction with the
HTTP proxy to provide Web-site filtering capabilities. It enables you to exert fine
control over the type of Web sites that users on your trusted network are allowed to
view.
For more information about WebBlocker and site blocking, see the WebBlocker
section of the Network Security Handbook.
How WebBlocker works
WebBlocker relies on a URL database built and maintained by SurfControl. The
WebBlocker database contains more than 65,000 IP addresses and 40,000 directories.
The database is copied to the WatchGuard WebBlocker site at regular intervals. The
Event Processor is automatically configured to download the most recent version of
the database from the WatchGuard WebBlocker site over an authorized channel. In
turn, the Firebox regularly queries the Event Processor for changes and, when
appropriate, downloads a new version and generates a log entry to show the transfer.
If the database is either corrupted, incompletely retrieved, or in any other way
incomplete, the Firebox does not load it. It repeats the attempt until it completes a
successful transfer.
When you restart your Firebox, all Web access is blocked for a brief period of time.
Users might receive the error message “Database not loaded” until the Firebox
downloads a database.
Reverting to old WebBlocker databases
To revert to a previous copy of the WebBlocker database, use the files named
Webblocker.old and Webblocker.old2 found in the installation directory. Rename the
files Webblocker.db and Weblocker.db2, respectively. The Firebox automatically
updates to the latest WebBlocker database the next time it queries Event Processor.

Configuring the WebBlocker service
Logging and WebBlocker
WebBlocker logs attempts to access sites blocked by WebBlocker. The log that is
generated displays information about source and destination address as well as the
blocked URL and the category that caused the denial.
WebBlocker also generates a log entry showing the results of any attempted database
retrieval, including whether or not it was successful and, if not successful, why.
Prerequisites to using WebBlocker
You need to complete several tasks before you can configure the Firebox to use
WebBlocker:
• Configure the WatchGuard service icon
Because WebBlocker relies on copying updated versions of the WebBlocker
database to the Event Processor, you must configure the WatchGuard service
setting Allow Outgoing to Any. It is possible to narrow this setting and use the IP
address of webblocker.watchguard.com. However, this address may change
without notice.
• Add some form of HTTP service icon
To use WebBlocker, add the Proxied-HTTP, Proxy, or HTTP service. WatchGuard
recommends using Proxied-HTTP, which provides filtering on all ports. (HTTP
without the Proxy service blocks only on port 80.) WebBlocker takes precedence
over other settings in the HTTP or Proxy services. If the HTTP service allows
outgoing from Any to Any but WebBlocker settings are set to “Block All URLs,”
all Web access is blocked. For information on adding an HTTP proxy service, see
Configuring the WebBlocker service
WebBlocker is a built-in feature of the service icons including HTTP, Proxied HTTP,
and Proxy. When WebBlocker is installed, five tabs appear in the HTTP service icon
dialog box:
• WebBlocker Controls
• WB: Schedule
• WB: Operational Hours
• WB: Non-Operational Hours
• WB: Exceptions

Click the WB: Operational Privileges tab.
Enable the content type checkboxes for the categories you would like to block.
For more information on WebBlocker Categories, see the Reference Guide.
Creating WebBlocker exceptions
Use exceptions to override any WebBlocker setting. Exceptions take precedence over
all other rules. These blocked URLs apply only to HTTP traffic and are not related to
the Blocked Sites list.
Exceptions are listed by IP address, but can be entered as domain names, network
addresses, or host IP addresses. You can fine-tune an exception by specifying a port
number, path, or string that is to be blocked for a particular Web site. For more
information on working with exceptions, see the WebBlocker section of the Network
Security Handbook.
From the HTTP Proxy dialog box:

CHAPTER 10
Setting Up Network Address
Translation
Network address translation (NAT) hides internal network addresses from hosts on
an external network. WatchGuard supports two types of NAT:
• Outgoing dynamic NAT
Hides network addresses from hosts on another network; works only on outgoing
messages.
• Incoming static NAT
Provides port-to-host remapping of incoming IP packets destined for a public
address to a single internal address; works only on incoming messages.
For more information on NAT, see the Network Security Handbook.
What is dynamic NAT?
Also known as IP masquerading or port address translation, dynamic NAT hides
network addresses from hosts on another network. Hosts elsewhere only see
outgoing packets from the Firebox itself. This feature protects the confidentiality and
architecture of your network. Another benefit is that it enables you to conserve IP
addresses.
WatchGuard implements two forms of outgoing dynamic NAT:
• Simple NAT – Using host aliases or IP host and network IP addresses, the
Firebox globally applies network address translation to every outgoing packet.
• Service-based NAT – Configure each service individually for outgoing
dynamic NAT.
Machines making incoming requests over a VPN connection are allowed to
access masqueraded hosts.
User Guide

Using simple dynamic NAT
Using simple dynamic NAT
In the majority of networks, the preferred security policy is to globally apply network
address translation to all outgoing packets. Simple dynamic NAT provides a quick
method to set NAT policy for your entire network.
Enabling simple dynamic NAT
The default configuration of simple dynamic NAT enables it from the Trusted
network to the External network. To enable simple dynamic NAT, use the Setup
Dynamic NAT dialog box. From Policy Manager:
1
2
Select Setup =>NAT.
Enable the Enable Dynamic NAT checkbox.
Adding dynamic NAT entries
Using built-in host aliases, you can quickly configure the Firebox to masquerade
addresses from your Trusted and Optional networks. For the majority of networks,
only a single entry is necessary:
• From: Trusted
• To: External
Larger or more sophisticated networks may require additional entries in the From or
To lists of hosts, or host aliases. The Firebox applies dynamic NAT rules in the order
in which they appear in the Dynamic NAT Entries list. WatchGuard recommends
prioritizing entries based on the volume of traffic that each represents. From the
Setup Dynamic NAT dialog box:
1
2
Click Add.
Use the From drop list to select the origin of the outgoing packets.
For example, use the trusted host alias to globally enable network address translation from the
3
4
Use the To drop list to select the destination of outgoing packets.
To add either a host or network IP address, click the ... button. Use the drop list to
select the address type. Enter the IP address. Network addresses must be entered
in slash notation.
5
Click OK.
The new entry appears in the Dynamic NAT Entries list.
Reordering dynamic NAT entries
To reorder dynamic NAT entries, select the entry and click either Up or Down. There
is no method to modify a dynamic NAT entry. Instead, use the Remove button to
remove existing entries and the Add button to add new entries.
64

Using service-based NAT
Using service-based NAT
Using service-based NAT, you can set outgoing dynamic NAT policy on a service-by-
service basis. Service-based NAT is most frequently used to make exceptions to a
globally applied simple dynamic NAT entry.
For example, use service-based NAT on a network with simple NAT enabled from
the Trusted to the Optional network with a Web server on the Optional network that
should not be masqueraded to the actual Trusted network. Add a service icon
allowing Web access from the Trusted to the Optional Web server, and disable NAT.
In this configuration, all Web access from the trusted network to the optional Web
server is made with the true source IP, and all other traffic from Trusted to Optional is
masqueraded.
You can also use service-based NAT in lieu of simple dynamic NAT. Rather than
applying NAT rules globally to all outgoing packets, you can start from the premise
that no masquerading takes place and then selectively masquerade a few individual
services.
Enabling service-based NAT
Service-based NAT is not dependent on enabling simple dynamic NAT. From Policy
Manager:
1
2
3
Select Setup =>NAT. Click Advanced.
Enable the Enable Service-Based NAT checkbox.
Click OK to close the Advanced NAT dialog box. Click OK to close the Dynamic
NAT dialog box.
Configuring service-based NAT exceptions
By default, services take on whatever dynamic NAT properties you have set for
simple NAT. However, you can override this setting in the service’s Properties dialog
box. There are three options:
• Use Default (Simple NAT) – Service-based NAT is not enabled for the
service. The service will use the simple dynamic NAT rules configured in the
• Disable NAT – Disables dynamic NAT for outgoing packets using this
service. Use this setting to create service-by-service exceptions to outgoing
NAT.
• Enable NAT – Enables service-based NAT for outgoing packets using this
service regardless of how the simple dynamic NAT settings are configured.
From Policy Manager:
1
Double-click the service icon. Click Outgoing.
If either simple dynamic NAT or service-based NAT is already enabled, an entry appears at the
bottom of the Outgoing tab.

Use the Choose Dynamic NAT Setup drop list to select either the default, disable,
or enable setting.

Configuring a service for incoming static NAT
Configuring a service for incoming static NAT
Static NAT works on a port-to-host basis. Incoming packets destined for a specific
public address and port on the External network are remapped to an address and
port behind the firewall. You must configure each service separately for static NAT.
Typically, static NAT is used for public services such as Web sites and e-mail that do
not require authentication.
Static NAT can be used only to forward connections from the outside to an internal
host. It is not possible for hosts already behind the Firebox to use the static NAT entry
when accessing an internal server. While hosts on the External interface of the Firebox
connect to the Firebox IP address and specified port (which then forwards the
connection internally), hosts on the inside of the Firebox must connect directly to the
actual, internal server IP address. This is usually only a problem when DNS is
involved. To avoid this problem, it is best to use a private DNS server (or static DNS
mapping, such as /etc/hosts for UNIX machines, or an Lmhosts file for Windows
machines) for internal hosts. This way, internal systems that try to connect to the
server by name will always get the internal IP address.
Adding external IP addresses
Static NAT converts a Firebox public IP and port into specific destinations on the
Trusted or Optional networks. If the Firebox has not already been assigned the public
IP address you want to use, you must designate a new public IP address using the
Add External IP dialog box. From Policy Manager:
1
2
3
4
Select Network => Configuration. Click the External tab.
Click Aliases.
At the bottom of the dialog box, enter the public IP address. Click Add.
Repeat until all external public IP addresses are added. Click OK.
Setting static NAT for a service
Static NAT, like service-based NAT, is configured on a service-by-service basis.
Because of the way static NAT functions, it is available only for services containing
TCP, UDP, FTP, SMTP, or HTTP. A service containing any other protocol cannot use
incoming static NAT, and the button in the service’s Properties dialog box is
disabled.

CHAPTER 11
Setting Up Logging and
Notification
Logging and notification are crucial to an effective network security policy. Together,
they make it possible to monitor your network security, identify both attacks and
attackers, and take action to address security threats and challenges.
Logging occurs when the firewall records the occurrence of an event to a log file.
Notification occurs when the firewall sends e-mail, pops up a window on the Event
Processor, or dials a pager to notify an administrator that WatchGuard detected a
triggering event.
WatchGuard logging and notification features are both flexible and powerful. You
can configure your firewall to log and notify on a wide variety of events, including
specific events at the level of individual services.
Ensure logging with failover logging
WatchGuard relies on failover logging to minimize the possibility of missing log
events. With failover logging, you configure a list of Event Processors to accept logs
in the event of a failure of the primary Event Processor. By default, the Firebox sends
log messages to the primary Event Processor. If for any reason the Firebox cannot
establish communication with the primary Event Processor, it automatically sends

WatchGuard logging architecture
log messages to the second Event Processor. It continues through the list until it finds
an Event Processor capable of recording events.
Multiple Event Processors operate in failover mode, not redundancy
mode—that is, events are not logged to multiple Event Processors
simultaneously; they are logged only to the primary Event Processor unless
that host becomes unavailable. Then the logs are passed on to the next
available Event Processor according to the order of priority. As soon as a
higher-priority Event Processor becomes available again, the logs are
shifted to that host. The highest-ranking Event Processor available always
receives the logs.
The LiveSecurity Event Processor software must be installed on each Event
Processor. For more information, see “Setting up the LiveSecurity Event
WatchGuard logging architecture
The flexible architecture of the Firebox System makes it possible to separate the
logging and notification responsibilities to multiple machines. By default, the Policy
Manager and the log and notification application – the LiveSecurity Event Processor
– are installed on the same computer. You can, however, install the Event Processor
software on a separate or multiple computers.
You must complete the following tasks to configure the firewall for logging and
notification:
Policy Manager
- Add logging and notification host(s)
- Customize preferences for services and packet handling options
- Save the configuration file with logging properties to the Firebox
LiveSecurity Event Processor
- Install the software on each Event Processor
- Set global logging and notification preferences for the host
- Set the log encryption key on the Event Processor identical to the key set in
Policy Manager.
Designating Event Processors for a Firebox
You should have at least one Event Processor to run the WatchGuard Firebox System.
The default primary Event Processor is the Management Station, which is set when

3
Click the host name. Click Remove.
Click OK.
The Logging Setup dialog box closes and removes the Event Processor entry from the

If you move the Event Processor to a host on another network
and change the Event Processor’s host address on the Firebox,
make sure to uninstall the Event Processor software from the
machine that is no longer the Event Processor host.
Reordering Event Processors
Event Processor priority is determined by the order in which they appear in the
LiveSecurity Event Processor(s) list. The host that is listed first receives log messages.
Use the Up and Down buttons to change the order of the Event Processors. From the
Logging Setup dialog box:
• To move a host down, click the host name. Click Down.
• To move a host up, click the host name. Click Up.
Synchronizing Event Processors
Synchronizing Event Processors is the act of setting the clocks of all your Event
Processors to a single common time source. Synchronizing Event Processors keeps
logs orderly and avoids time discrepancies in the log file if failovers occur.
The Firebox sets its clock to the current Event Processor. If the Firebox and the Event
Processor time are different, the Firebox time drifts toward the new time, which often
results in a brief interruption in the log file. Rebooting the Firebox resets the Firebox
time to that of the primary Event Processor. Therefore, you should set all Event
Processors’ clocks to a single source. In a local installation where all Event Processors
are on the same domain, set each Event Processor to the common domain controller.
For Windows NT Event Processors
1
Go to each Event Processor. Open an MS-DOS Command Prompt window. Type
the following command:
net time /domain:domainName /set
where domainName is the domain in which the Event Processors operate.
The system returns a message naming the domain controller.
2
Type Y.
The time of the local host is set to that of the domain controller.

Setting up the LiveSecurity Event Processor
Another way to set the Event Processor (and domain controller) clocks is to use an
independent source such as the atomic clock—based servers available on the Internet.
One place to access this service is:
Setting up the LiveSecurity Event Processor
The LiveSecurity Event Processor controls logging and notification. It also provides
scheduling services for the Firebox; if the Event Processor is not running, you may be
unable to connect to the Firebox.
Installing the Event Processor program
The LiveSecurity Event Processor program is separate from the WatchGuard Control
Center and Policy Manager. It must be installed and the log encryption key entered
on all Event Processors. Although it can be installed on the Management Station
during the QuickSetup wizard installation process, you must also install and run it on
any additional Event Processors.
The LiveSecurity Event Processor program is available both as a command-line utility
and, on a Windows NT host, as a service. During installation, the setup utility detects
whether or not the host is operating Windows NT or Windows 2000. If so, it installs
the program as a service that automatically starts when you restart the machine:

Run the WatchGuard Firebox System installation wizard.
When the wizard asks if you would like to set up logging and notification, select
Yes.
Running an Event Processor on Windows 98
If the Event Processor is to be run on a Windows 98 operating system, it must be run
from the command line in a DOS window or directly from the Startup folder. A DOS
window stays open as long as the LiveSecurity Event Processor is running. If you
must log off a Windows 98 Event Processor, the program exits and logging will not
work. On the Event Processor host:

Customizing logging and notification by service or option
The Firebox System allows you to create custom logging and notification properties
for each service and blocking option. You can fine-tune your security policy, logging
only those events that require your attention and limiting notification to truly high-
priority events.
To make logging and notification configuration easier, services, blocking categories,
and packet-handling options share an identical dialog box. Therefore, once you learn
the controls for one type of service, you can easily configure the remainder.
The Logging and Notification dialog box contains the following controls:
Category
The event types that can be logged by the service or option. This list changes
depending on the service or option. Click the event name to display and set its
properties.
Enter it in the log
Enable this checkbox to log the event type; clear it to disable logging for the
event type. Because the Firebox must perform domain name resolution, there
may be a time lag before logs appear in the log file. All denied packets are
logged by default.

Custom Program
Triggers a custom program when the event occurs. WatchGuard allows only
one notification type per event. A custom batch file or program enables you to
trigger multiple types of notification. Type the full path to the program in the
accompanying field, or use Browse to locate and select the program.
Setting Launch Interval and Repeat Count
There are two parameters that work in conjunction with the Event Processor Repeat
Interval to control notification timing:
Launch Interval
The minimum time (in minutes) between separate launches of a notifier. Set
this parameter to prevent the launch of several notifiers in response to similar
events that take place in a short amount of time.
Repeat Count
The threshold for how often a notifier can repeat before the Firebox activates
the special repeat notifier. The repeat notifier creates a log entry that the
notifier in question is repeating. Notification repeats only after this number of
events occurs.
For an example of how launch interval and repeat count interact, see the Network
Security Handbook.
Setting logging and notification for a service
For each service added to the Services Arena, you can control logging and notification
of the following events:
• Incoming packets that are allowed
• Incoming packets that are denied
• Outgoing packets that are allowed
• Outgoing packets that are denied

Connect with Out-of-Band
Management
The WatchGuard Firebox System out-of-band (OOB) management feature enables the
Management Station to communicate with a Firebox by way of a modem and
telephone line. OOB is useful for remotely configuring a Firebox when access via the
Ethernet interfaces is unavailable.
Connecting a Firebox with OOB management
To connect to the Firebox using OOB management, you must:
• Connect the Management Station to a modem – Connect a modem between
the serial port on the Management Station and an analog telephone line.
• Connect the Firebox modem – Connect an external or PCMCIA (also known as
PC Card) modem to the Firebox. External modems must be attached to the
CONSOLE port of the Firebox.
• Enable the Management Station for dial-up networking connections.
• Set Firebox network configuration properties.
Enabling the Management Station
For a dial-up PPP connection to work between a Management Station and a Firebox,
you must configure the Management Station to use a PPP connection. In Windows
NT, Windows 95/98, and Windows 2000, PPP is the default protocol used by Dial-Up
Networking. There are separate procedures for configuring a PPP connection on the
Windows NT, Windows 95/98, and Windows 2000 platforms.

PART IV Administering a Security Policy
Network security is more than just designing and implementing a security policy and
copying the resulting configuration file to a WatchGuard Firebox. Truly effective
network security requires constant vigilance and ongoing adaptation to changing
business needs. WatchGuard provides the following functionality for administering
your security policy:
Aliases and Authentication
Control access to services by requiring users to identify themselves. In
addition to our own authentication scheme, WatchGuard also supports
Windows NT, RADIUS, CRYPTOCard, and SecurID server authentication.
Use host aliases to speed configuration of authentication and service
properties.
Firebox Activity Monitors
Firebox Monitors displays real-time traffic through your Firebox. View
bandwidth usage, dynamically and manually blocked sites, and Firebox
status. Use HostWatch to monitor active connections and LogViewer to read
and print a log file.
Network Activity Reports
Use the Web-based Historical Reports utility to build, display, modify, and
print reports of activity through the Firebox.

CHAPTER 13
Creating Aliases and
Implementing Authentication
Aliases are shortcuts used to identify groups of hosts, networks, or users with one
name. The use of aliases simplifies user authentication and service configuration.
User authentication provides access control for outgoing connections. Authentication
dynamically maps an individual username to a workstation IP address, allowing the
tracking of connections based on name rather than static IP address.
For more information on aliases or authentication, see the Network Security Handbook.
Using host aliases
Host aliases provide a simple way to remember host IP addresses, host ranges,
groups, usernames, and network IP addresses. They function in a similar fashion to e-
mail distribution lists–combining addresses and names into easily recognizable
groups. Use aliases to quickly build service filter rules or configure authentication.
Aliases cannot, however, be used to configure the network itself.
WatchGuard automatically adds four host aliases to the basic configuration:
firebox
trusted
optional
external
Addresses assigned to the three Firebox interfaces
Any host or network routed through the physical Trusted interface
Any host or network routed through the physical Optional interface
Any host or network routed through the physical External interface; in
most cases, the Internet
A host alias takes precedence over a Windows NT or RADIUS group with
the same name.

What is user authentication?
What is user authentication?
User authentication allows the tracking of connections based on name rather than IP
address. With authentication, it no longer matters what IP address is used or from
which machine a person chooses to work; the username defines the permissions of
the user, and follows the user from workstation to workstation.
To gain access to Internet services (such as outgoing HTTP or outgoing FTP), the user
provides authenticating data in the form of a username and password. For the
duration of the authentication, the session name is tied to connections originating
from the IP address from which the individual authenticated.
For more information about authentication, see the Network Security Handbook.
User authentication types
The WatchGuard Firebox System supports five authentication methods identified by
the server type used:
• Firebox
• Windows NT
• RADIUS
• CRYPTOCard
• SecurID
A client performs the same sequence of tasks to authenticate against any of the five
types of authentication. For the administrator, the Firebox method requires the
administrator to add usernames, passwords, and groups using Policy Manager, while
the other four methods require storing the data on the server performing
authentication.
While more than one type of authentication scheme can be implemented, only
one type of authentication can be applied to a single user session.
How user authentication works
A specialized-HTTP server runs on the Firebox. To authenticate, clients must connect
to the authentication server using a Java-enabled Web browser pointed to
http://IP address of any Firebox interface:4100/
A Java applet loads a prompt for a username and password that it then passes to the
authentication server using a challenge-response protocol. Once successfully
authenticated, users minimize the Java applet and browser window and begin using
allowed network services.
As long as the Java window remains active (it can be minimized but not closed) and
the Firebox doesn’t reboot, users remain authenticated until the session times out. To
prevent an account from authenticating, disable the account on the authentication
server.

network happens from one location.
To add or remove services accessible by RADIUS authenticated users, add the
RADIUS user or group in the individual service properties dialog box, and the IP
address of the Firebox on the RADIUS authentication server.
Although WatchGuard supports both CHAP and PAP authentication, CHAP is
considered more secure.

If you are using a backup server, enable the Specify backup SecurID server
checkbox. Enter the IP address and port number for the backup server.
Click OK.
Using authentication to define remote user VPN access
WatchGuard uses two built-in Firebox groups to identify currently active remote user
virtual private network users.
• pptp_users – Names authorized to use Remove User VPN with PPTP
• ipsec_users – Names authorized to use Mobile User VPN with IPSec
When a user successfully connects to the Firebox using Remote User VPN,
WatchGuard automatically adds the assigned IP address to one of these built-in
aliases (depending on the VPN method). When the user shuts down the VPN session,
WatchGuard automatically removes the address associated with that user from the
alias.
When a Remote User VPN connection is made to the Firebox, WatchGuard checks the
client’s username and password against the Firebox domain. For this reason, Remote
User VPN users must have an account in the Firebox domain and must be a member
of the appropriate VPN group for access, regardless of any other authentication
scheme in use.
When users authenticate using their account in the Firebox domain, WatchGuard
automatically adds their IP address to all Firebox domain groups of which they are a
member, including pptp_users or ipsec_users.
By default, Remote User VPN users (or any users) have no access privileges through a
Firebox. To allow Remote User VPN users to access machines on the Trusted
network, you must add their usernames (or the group alias) to service icons in the
Services Arena.
A typical use of built-in groups is to allow incoming connections to certain Trusted
servers from the pptp_users or ipsec_users group members. This is an easy way to
provide outside access to critical machines inside your network, without
compromising general security.
Example: Configuring a service for Remote User VPN
To allow outgoing Telnet but only allow incoming Telnet if the request comes from a
Remote User VPN user, follow this procedure:
From Policy Manager:
1
Add a Telnet icon to the Services Arena if one does not already exist.
2
3
4
Configure the Outgoing tab to allow from Any to Any.
Configure the Incoming tab to allow from pptp_users to Any.
Click OK.

CHAPTER 14
Monitoring Firebox Activity
An important part of an effective network security policy is the monitoring of
network events. Monitoring enables you to recognize patterns, identify potential
attacks, and take appropriate action. If an attack occurs, the records kept by
WatchGuard will help you reconstruct what happened.
The extensive logging provided with the Firebox System can also be useful in
debugging network services, solving routing problems, and identifying other
network configuration problems.
Firebox Monitors and HostWatch are two tools for monitoring traffic through the
Firebox.
Firebox Monitors
Firebox Monitors is a user interface providing several real-time displays of activity
through the Firebox.
Starting Firebox Monitors and connecting to a Firebox
From Control Center:
1
On the QuickGuide, click the Firebox Monitors button (shown at
right).
Firebox Monitors opens and displays the Bandwidth Meter tab. There is no active
connection to a Firebox.
2
3
Select File =>Connect. Or, on the Firebox Monitors toolbar, click Connect.
Enter a Firebox name or IP address, or use the Firebox drop list to select a Firebox.
Enter the monitoring (read-only) pass phrase. Click OK.
Firebox Monitors displays traffic patterns on the selected Firebox.

Authentication list
The Authentication List tab displays the host IP addresses and user names of
everyone currently authenticated to the Firebox. If you are using DHCP, the IP
address—to—user name mapping changes whenever machines restart.
Blocked Sites list
The Blocked Sites List tab lists the IP addresses (in slash notation) of any external
sites that are temporarily blocked by port space probes, spoofing attempts, address
space probes, or another event configured to trigger an auto-block.
Next to each blocked site is the amount of time remaining on the temporary auto-
block. You can adjust the auto-blocking value from the Blocked Sites dialog box
available through Policy Manager.
You can selectively remove sites from this blocked list either by selecting the site and
clicking the X toolbar button or by double-clicking a site. If the display is in
continuous refresh mode (that is, if the Continue button on the toolbar is active),
selecting a site on the list or clicking the X button stops the refresh mode. (The X and
Continue buttons are grayed out unless the Blocked Sites list is shown.)
If you opened the Firebox with the monitoring (read-only) passphrase, Firebox
Monitors prompts you to enter the configuration (read-write) passphrase before
removing a site from the list.
HostWatch
HostWatch is a real-time display of active connections occurring on a Firebox. It can
also graphically represent the connections listed in a log file, either playing back a
previous file for review or displaying connections as they are logged into the current
log file. HostWatch provides graphical feedback on network connections between the
trusted and external networks as well as detailed information about users,
connections, and network address translation.

HostWatch
The HostWatch display uses the logging settings configured for your Firebox using
the Policy Manager. For instance, to see all denied attempts at incoming Telnet in
HostWatch, configure the Firebox to log incoming denied Telnet attempts.
The line connecting the source host and destination host is color-coded to display the
type of connection being made. These colors can be changed. The defaults are:
• Red – The connection is being denied.
• Blue – The connection is being proxied.
• Green – The connection is using network address translation (NAT).
• Black – The connection falls into none of the first three categories.
Representative icons appear next to the server entries for HTTP, Telnet, SMTP, and
FTP.
Name resolution might not occur immediately when you first start HostWatch. As
names are resolved, HostWatch replaces IP addresses with host or usernames,
depending on the display settings. Some machines might never resolve, and the IP
addresses remain in the HostWatch window.
To start HostWatch, click the HostWatch icon (shown at left) on the
Control Center QuickGuide.
HostWatch display
The upper pane is split into two sides, Inside and Outside. Double-click an item on
either side to produce a pop-up window displaying detailed information about

CHAPTER 15
Reviewing and Working with Log
Files
Log entries are stored on the primary and backup LiveSecurity Event Processor. By
default, log files are placed in the WatchGuard installation directory in a subdirectory
called \logs. The log file to which the Event Processor is currently writing records is
named Firebox IP.wgl. In addition, the Event Processor creates an index file in the
same directory by the same name with the extension .idx. When Event Processor rolls
a log file over, it saves the old files as Firebox IP Time Stamp.wgl and Firebox IP Time
Stamp.idx.Both the .wgl and .idx files are necessary to use any monitoring or log
display tool.
For more information about the LiveSecurity Event Processor and configuring
logging, see “Setting Up Logging and Notification” on page 69.
Viewing files with LogViewer
The WatchGuard Firebox System utility called LogViewer provides a dynamic
display of log file data. You can view all log data page by page, or search and display
by keyphrases or specific log fields.

Additional information appears after the previously described fields,
including data about IP fragmentation, TCP flag bits, IP options, and source
file and line number when in trace mode. If WatchGuard logging is in debug
or verbose mode, additional information is reported. In addition, the type of
connection may be displayed in parentheses. Default = Show
Working with log files
The Firebox is continually writing messages to log files on the LiveSecurity Event
Processor. Because current log files are always open, they cannot be copied, moved,
or merged using traditional copy tools; you should use LiveSecurity Event Processor
utilities to work with active log files.
Unlike with other Firebox System utilities, you cannot access the LiveSecurity Event
Processor user interface from Control Center. To open the Event Processor user
interface:
• Right-click the Event Processor icon in the Windows system tray and select
Open Log Center.
Consolidating logs from multiple locations
You can merge two or more log files into a single file. This merged file can then be
used with Historical Reports, LogViewer, HostWatch, or some other utility to
examine log data covering an extended period of time. From the LiveSecurity Event
Processor:

CHAPTER 16
Generating Reports of Network
Activity
Historical Reports is a reporting tool that creates summaries and reports of Firebox
log activity. It generates these reports using the log files created by and stored on the
LiveSecurity Event Processor. Use Historical Reports to define reports, create filters,
and process reports for viewing in a standard Web browser.
You can customize reports to include exactly the information you need in a form that
is most useful to you. Using Historical Reports special features, you can define a
precise time period for a report, consolidate report sections to show activity across a
group of Fireboxes, and set properties to display the report data according to your
preferences.
Starting Historical Reports
From Control Center:
1
Click the Historical Reports icon (shown at right).
You can also start Historical Reports from the WatchGuard installation
directory. The file name is WGReports.exe.
Viewing the reports list
To view all reports generated, click Reports Page. This launches your default browser
with the HTML file containing the main report list. You can navigate through all the
reports in the list.
Creating and editing reports
Use Historical Reports to design reports that specifically address the requirements of
your network security policy. You can customize reports by selecting sections to
include, consolidating report sections, specifying time filters, defining user and host
filters, and setting where and how the report is generated.

Using report filters
By default, a report displays information on the entire contents of a log file. There
may be times, however, when you want to view only information about specific
hosts, services, or users. Use report filters to narrow the range of data reported upon.
Filters can be one of two types:
Include
Creates a report that includes only those records that meet the criteria set in
the Host, Service, or User Report Filters tabs.
Exclude
Creates a report that excludes all records that meet the criteria set in the Host,
Service, or User Report Filter tabs.
You can filter an Include or Exclude report based on three criteria:
Host
Filter a report based on host IP address.
Port
Filter a report based on service name or port number.
User
Filter a report based on authenticated username.
Creating a new filter

PART V WatchGuard Virtual Private
Networking
A virtual private network (VPN) allows the secure tunneling of data between two
networks (or a host to a network) via a third unprotected network. The WatchGuard
Firebox System includes two methods to provide secure tunnels:
Branch office virtual private network
Use the WatchGuard Branch Office VPN features to securely connect two or
more locations over the Internet. You can take advantage of our WatchGuard
VPN Firebox-to-Firebox configuration or implement a WatchGuard Firebox—
to—IPSec-compliant device tunnel.
Remote user virtual private network
Create a secure connection between the trusted network and an employee
traveling or working from home with either Point to Point Tunneling Protocol
(PPTP) or using an IPSec tunnel. WatchGuard Remote User VPN with PPTP
feature is included with the basic software package. WatchGuard Mobile User
VPN with IPSec feature is an option.

CHAPTER 17
Configuring Branch Office Virtual
Private Networking
Branch office virtual private networking (VPN) creates a secure tunnel, over an
unsecure network, between two networks protected by the WatchGuard Firebox
System or between a WatchGuard Firebox and an IPSec-compliant device. Using
branch office VPN, you can connect two or more locations over the Internet while still
protecting the resources of your trusted and optional networks.
WatchGuard offers three branch office VPN methods:
• DVCP VPN
This method defines a Firebox as a DVCP server at the center of a distributed
array of WatchGuard Firebox and SOHO clients.
• IPSec (Internet Protocol Security)
This method uses IPSec to tunnel between a WatchGuard Firebox and an IPSec-
compliant device from another vendor or between two Fireboxes.
• WatchGuard VPN
This method uses the WatchGuard proprietary secure connection, called
WatchGuard VPN, to create a tunnel between two WatchGuard Fireboxes.
A given pair of Fireboxes can establish only one VPN connection between
them. However, a single Firebox can tunnel to multiple branch locations.
Incoming connections from branch office VPN networks can access machines
on the Trusted interface regardless of whether the local machines are using
NAT.
Connections made through a branch office VPN are exempt from Simple
NAT.
Addresses used for VPN must not be on the Blocked Sites list.
Configuration checklist
Before implementing branch office VPN, gather the following information:
• IP address of both ends of the tunnel.
User Guide
121
Download from Www.Somanuals.com. All Manuals Search And Download.
Using DVCP to connect to devices
• IP network addresses for the networks communicating with one another.
• A common passphrase, known as a shared secret.
• For WatchGuard VPN only, the local VPN IP address of each Firebox. It must
be selected from a reserved network address that is not in use on either of the
networks being connected. For more information, see RFC 1918 or “Setting Up
Both ends of the tunnel must use the same encryption method.
Using DVCP to connect to devices
Dynamic VPN Configuration Protocol (DVCP) is the WatchGuard-proprietary
protocol that easily creates a virtual private network. The DVCP server is a Firebox
that sits at the center of a distributed array of WatchGuard Firebox, SOHO, and
SOHO|tc clients.
How does DVCP work?
The DVCP option causes the Firebox to act as a server. SOHOs can be DVCP clients,
and Fireboxes can either be DVCP clients or servers. The DVCP server maintains the
connections between two devices by storing all policy information–including
network address range and tunnel properties such as encryption, timeouts, and
authentication. DVCP clients can retrieve this information from the server. The only
information clients need to maintain is an identification name, shared key, and the IP
address of the server External interface.
You use the the DVCP Client Wizard to configure a device as a DVCP server and then
create tunnels to each client Firebox or SOHO. The clients then contact the server and
automatically download the information needed for them to connect securely.
Basic and Enhanced DVCP
WatchGuard offers two types of DVCP:
Basic DVCP simplifies establishing VPN tunnels between SOHO units and
Fireboxes. It cannot manage tunnels between two Fireboxes.
Enhanced DVCP manages tunnels between any two WatchGuard devices: SOHO to
Firebox, Firebox to Firebox, and so on. Enhanced DVCP is available only if the VPN
Manager 2.0 option is installed.
Creating a tunnel to a SOHO or SOHO|tc
The tunnels you create for SOHO clients must be completely distinct from any tunnel
created for branch office VPN. In other words, no addresses in the DVCP client policy
should be in the same address range as any branch office policy.

Using DVCP to connect to devices
Note also that if you configure a SOHO for both Basic and Enhanced DVCP, the
gateway names must be different.

and/or time in hours.
The default values are 8192 kilobytes or 24 hours.
11 Click Next. Click Finish.
The new policy appears in the DVCP Configuration dialog box. The WatchGuard device can now
be connected, powered on, and configured. As part of the configuration process, it will
automatically download the appropriate tunnel information. You must provide the DVCP client
administrator with the Client Name, shared key, and the server external interface IP address.
Editing a tunnel to a device
It is possible to change the properties of a DVCP tunnel without adversely impacting
the DVCP client. Properties of a tunnel that you can modify without forcing the client
to reboot include:
• Identification name
• Shared key
• Encryption/authentication level
• Timeouts

automatically restarts.
Removing a tunnel to a device
When a tunnel is removed, the DVCP client can no longer communicate with the
server. The next time the DVCP client tries to contact the server, contact will be
denied. If these settings were never manually configured, the client will use
192.168.111.0/24 as the DHCP network range.

Creating an IPSec policy
Policies are sets of rules, much like packet filter rules, for defining how outgoing
IPSec packets are built and sent and determining whether incoming IPSec packets can
be accepted. Policies are defined by their endpoints. These are not the same as tunnel
or gateway endpoints–they are the specific hosts or networks attached to the
tunnel’s Fireboxes (or other IPSec-compliant device) that communicate through the
tunnel.
From the IPSec Configuration dialog box:
1
2
Click Add.
Use the Local drop list to select the tunnel type of the IP address behind the local
Firebox.
The tunnel type can be an entire network or a single host.
3
4
Enter the IP or network address in slash notation for the local host or network.
Use the Remote drop list to select the tunnel type of the IP address of the remote
Firebox or IPSec-compliant device.
5
6
Enter the IP address or network address in slash notation for the remote host or
network.
Use the Disposition drop list to select a bypass rule for the tunnel:
Secure
IPSec will encrypt all traffic that matches the rule in associated tunnel policies.
Block
IPSec will not allow traffic that matches the rule in associated tunnel policies.
Bypass
IPSec will not allow traffic that matches the rule in associated tunnel policies.
You cannot bypass a policy that has a network at either endpoint.
For every tunnel created to a dropped-in device, you must create a host policy
for both sides’ external IP addresses with protection set to Bypass. Otherwise,
traffic to and from the dropped-in device’s external IP address will conflict
with any network policy associated with the VPN.

initially listed in the order in which they were created.
Changing IPSec policy order
WatchGuard handles policies in the order listed, from top to bottom, on the IPSec
configuration dialog box. Initially, the policies are listed in the order created. You
must manually reorder the policies from more specific to less specific to ensure that
sensitive connections are routed along the higher-security tunnels. In general,
WatchGuard recommends the following policy order:
• Host to host
• Host to network
• Network to host
• Network to network
Policies must be set to the same order at both ends of the tunnel. For more
information about IPSec policy order, see the Network Security Handbook.
From the IPSec Configuration dialog box:
• To move a policy up in the list, click the policy. Click Move Up.
• To move a policy down in the list, click the policy. Click Move Down.
Configuring services for branch office VPN with IPSec
Users on the remote Firebox are technically outside the trusted network; you must
therefore configure the Firebox to allow traffic through the VPN connection. A quick
method is to create a host alias corresponding to the VPN remote networks and hosts.
Then, use either the host alias or individually enter the remote VPN networks and
hosts when configuring the following service properties:
Incoming
• Enabled and Allowed
• From: Remote VPN network, hosts, or host alias
• To: trusted or selected hosts
Outgoing
• Enabled and Allowed
• From: trusted network or selected hosts
• To: Remote VPN network, hosts, or host alias

Configuring WatchGuard VPN
Allow VPN access to any services
To allow all traffic from VPN connections, add the Any service to the Services Arena
and configure it as described above.
Allow VPN access to selective services
To allow traffic from VPN connections only for specific services, add each service to
the Services Arena and configure each as described above.
Access control is a critical part of configuring a secure VPN environment. If
machines on the branch office VPN network are compromised, attackers
obtain a secure tunnel to the trusted network.
Configuring WatchGuard VPN
Use WatchGuard VPN to implement branch office VPN between two Fireboxes.
WatchGuard VPN uses udp port 4104.
WatchGuard VPN offers 40-bit encryption. WatchGuard VPN with 128-bit
encryption can be used when both ends of the tunnel are licensed for enhanced
encryption. Other encryption standards are available (128-bit DES and 3-
DES).
WatchGuard VPN configuration models
There are two models for configuring WatchGuard VPN:
Two-box configuration
Connect two networks over the Internet using two Fireboxes.
Multiple box configuration
Connect one central Firebox to multiple remote networks over the Internet.
- Add multiple VPN configurations to the central Firebox, and configure
remote Fireboxes accordingly.
- Make sure that passphrases are unique to a single VPN connection.
- On the central Firebox, use the same IP address for multiple remote
Fireboxes. However, the address can not be used for another purpose on
either the central or remote networks.
Setting up WatchGuard VPN

In the Local Firebox IP field, enter an IP address from a reserved network not in
use on the local or remote networks.
More information on reserved networks can be found in RFC 1918. You can
use the same local VPN IP address for multiple VPN connections when
specifying more than one—for example, when there are several branch offices
connecting to a central office.
In the text box to the left of the Add button, enter the IP address in slash notation
of any remote network to which access should be granted from the local Firebox .
Click Add.
The remote Firebox must reciprocate by adding the local networks in its Remote Networks box.
Because WatchGuard VPN is a peer-to-peer situation, each Firebox must have the other’s
network listed.

Click the Encryption tab.
Under Encryption, select the number of bits used to encrypt the tunnel.
The greater the number of bits, the stronger the encryption.
8
Enter the encryption key. Click Make Key.
WatchGuard hashes the encryption key and then displays a key in the bottom panel.
The hashed key must be identical on both Fireboxes. If you are running
different versions of WatchGuard Security System software, verify that the
hashes match exactly on the two Fireboxes.
9
Click the Options tab.
10 Enable the Activate WatchGuard VPN checkbox.
11 To automatically block sites when the source fails to properly connect to the
Firebox, enable the Add Source to Blocked List When Denied checkbox.
12 Enable Logging options according to your security policy preferences.
Activating logging often generates a high volume of log entries, significantly slowing the passage
of VPN traffic. WatchGuard recommends logging only for debugging purposes.
Changing remote network entries
You cannot edit a remote network entry. You must remove the original and add the
new remote network address. From the WatchGuard VPN Setup dialog box:
1
2
Click the network address. Click Remove.
Click Add.
Add the new network configuration.
Preventing IP spoofing with WatchGuard VPN
There is a potential IP spoofing problem if the remote Firebox IP is on the same
network as a remote network. It is theoretically possible to spoof packets from that
single IP address (the remote Firebox IP). Although this situation is relatively rare,
you can prevent it by disallowing access to internal servers from the remote Firebox
IP.

Configuring WatchGuard VPN
Configuring incoming services to allow VPN
Because users on the remote Firebox are technically outside the trusted network, you
must configure services to allow traffic through the VPN connection. WatchGuard
recommends the following method:
1
Create a host alias corresponding to the VPN remote networks.
2
Add the VPN host alias to Incoming and From Outgoing to properties of allowed
services.
An alternative method is to add the Any service with the following incoming
properties:
• Enabled and allowed
• From: VPN host alias
• To: Any
Verifying successful WatchGuard VPN configuration
To determine whether a configuration has been successful:
• Watch for log entries as the Firebox reboots that show local and remote VPN IP
addresses.
• Check the Firebox status once it has booted. There should be an entry for a VPN
interface directly following the entry for eth2.
• Check the Control Center display for tunnel status.
If none of these indicators is present, review all settings on both Fireboxes, double-
check that the passphrases are the same, and verify the remote IP addresses.

CHAPTER 18
Configuring the Firebox for
Remote User VPN
Remote user virtual private networking (RUVPN) establishes a secure connection
between an unsecured remote host and a protected network over an unsecured
network. RUVPN connects an employee on the road or working from home to trusted
and optional networks behind a Firebox using a standard Internet dial-up connection
without compromising security.
WatchGuard Firebox System offers two types of RUVPN:
Remote User PPTP
Uses the Point-to-Point Tunneling Protocol. This type of RUVPN is included
with the basic WatchGuard package and supports up to 50 concurrent
sessions per Firebox. Works with any Firebox encryption level.
Mobile User VPN
Uses Internet Protocol Security. This type of RUVPN is an optional feature of
the WatchGuard package. It requires strong or medium encryption.
RUVPN requires configuration of both the Firebox and the end-user remote host
computers. This section describes how to configure a Firebox for both types of
RUVPN. For information on configuring the remote host, see “Preparing a Host for
Remote User PPTP and Mobile User VPN require that the Management
LiveSecurity Service Web site at http://www.watchguard.com/support.
Configuration checklist
Before configuring a Firebox to use remote user virtual private networking (RUVPN),
gather the following information:
• The IP addresses to assign to the remote client during RUVPN sessions. The IP
addresses cannot be addresses currently in use in the network.
User Guide
133
Download from Www.Somanuals.com. All Manuals Search And Download.
Configuring shared servers for RUVPN
• The IP addresses of the DNS and WINS servers in the trusted network that
perform IP address lookup on host alias names.
• The usernames and passwords of those authorized to connect to the Firebox
using RUVPN.
• For Mobile User VPN, you will also need:
- Mobile User VPN license key
- Target Firebox upgraded to strong or medium encryption
Configuring shared servers for RUVPN
RUVPN clients rely on shared Windows Internet Name Server (WINS) and Domain
Name System (DNS) server addresses. For information on configuring these servers,
Adding remote access users
The Firebox configuration file automatically includes two Firebox User groups called
pptp_users and ipsec_users. When a remote host connects and creates a tunnel,
Policy Manager authenticates the username against the list of members for the group
associated with the tunnel type. In other words, an incoming PPTP tunnel would
authenticate against the pptp_users group.
Once authenticated, the Policy Manager then adds the remote client IP address to the
group. Use the Firebox User group to configure services for incoming and outgoing
RUVPN traffic.
Because of the way Windows holds the username and password for subsequent
logins, one option to reduce end-user confusion is to assign the same RUVPN login
and password as those used for Windows NT login and password. This method,
however, is less secure than using multiple passwords.
RUVPN users must be added as Firebox users even if another authentication
method is used internally.
Adding a member to built-in RUVPN user groups
The process to add a member to the built-in RUVPN user groups is the same for both
PPTP and IPSec. The example below is for pptp_users. From Policy Manager:
1
2
Select Setup =>Authentication.
Click the Firebox Users tab. To add a new user, click the Add button beneath the
Users list.
There is also a button to access the Setup Firebox User dialog box from within the Mobile User
VPN wizard.

By individual service
Double-click each service that you want to enable for your remote VPN users. Set the
following properties on the service:
Enable permissions for pptp_users if you are configuring Remote User PPTP.
Enable permissions for ipsec_users if you are configuring Mobile User VPN.
Incoming
- Enabled and allowed
- From: pptp_users or ipsec_users
- To: Any (or selected)

Configuring the Firebox for Remote User PPTP
- From: Selected
- To: pptp_users or ipsec_users
Configuring the Firebox for Remote User PPTP
Configuring the Firebox for Remote User PPTP requires that you perform the
following:
• Enter IP addresses and networks used for clients
• Add usernames to the built-in Firebox User group pptp_users
• Activate the Remote User PPTP feature
• Configure service properties using pptp_users
• Verify WINS and DNS server settings
Activating Remote User PPTP
If you want to set up RUVPN for users behind a Firebox (connecting to
another Firebox), they must be on a public subnet, and the wg_pptp service
icon must be added in the Services Arena. Or, create a BOVPN tunnel.
The first step to configuring Remote User PPTP is to activate the feature. Activating
Remote User PPTP adds the wg_pptp service icon to the Services Arena. The icon is
visible only in the Advanced view of Policy Manager. The wg_pptp icon rarely
requires modification. WatchGuard recommends leaving wg_pptp in its default
settings. From Policy Manager:
1
2
3
Select N e t w o r k => R e m o t e U s e r. Click the PPTP tab.
Enable the Activate Remote User checkbox.
If necessary, enable the Enable Drop from 128-bit to 40-bit checkbox.
In general, the encryption drop control is used only by international customers.
Entering IP addresses for Remote User sessions
Remote User PPTP supports only 50 concurrent sessions, but you can configure a
virtually unlimited number of client computers. The Firebox dynamically assigns an
open IP address to each incoming RUVPN session from a pool of available addresses
until this number is reached. After the user closes a session, the address reverts to the
available pool and can be assigned to the next user who attempts to log on.
Use Policy Manager to assign individual addresses or a single network to the
available pool. The safest method is to fabricate a Secondary Network address (see
“Adding a secondary network” on page 38) and choose the IP addresses from that
network range. That way, you draw from a range of addresses already declared to
Policy Manager, but which cannot clash with real host addresses in use behind the
Firebox. Using this method, you must also configure the client machine to use the
default gateway on the remote host (see “Configuring the remote host for RUVPN

In the Value field, enter the host or network address in slash notation. Click OK.
Enter unused IP addresses that the Firebox can dynamically assign to clients during Remote
User PPTP sessions. Selected addresses must not appear in the Blocked Sites list. The IP
address appears in the list of addresses available to remote clients.
Repeat the add process until you have configured all addresses for use with
Remote User PPTP.
Rules for valid Remote User PPTP addresses
• Addresses that have host routes are invalid
• Traffic routed through the default gateway does not receive proxy ARP
treatment
• Addresses whose packets would be routed through the External interface (but
not through the default gateway) are invalid
• Addresses in networks to which you have routes are invalid (except those that
are routed through default route)
• Any other packets are allowed and handled by proxy ARP
Configuring the Firebox for Mobile User VPN
Mobile User VPN requires careful configuration of both the Firebox and the remote
client computers. However, unlike Remote User PPTP, the Firebox administrator
retains more control over the client configuration through an end-user configuration
file. Configuring the Firebox for Mobile User VPN requires the following steps:
• Obtain a license key from WatchGuard
• Add user names to the built-in Firebox group ipsec_users
• Enter the IPSec license key into the Firebox configuration file
• Verify WINS and DNS server settings
• Use Policy Manager to simultaneously configure the Firebox and create end-
user configuration files
• Configure service properties using ipsec_users
• Distribute the end-user configuration files along with the RUVPN client
software and documentation

CHAPTER 19
Preparing a Host for Remote
User VPN
Remote user virtual private networking (RUVPN) establishes a secure connection
between an unsecured remote host and a protected network over an unsecured
network. RUVPN connects an employee on the road or working from home to trusted
and optional networks behind a Firebox using a standard Internet dial-up connection
without compromising security.
The WatchGuard Firebox System offers two types of RUVPN:
• Remote User PPTP – Uses the Point-to-Point Tunneling Protocol. This type of
RUVPN is included with the basic WatchGuard package and supports up to 50
concurrent sessions per Firebox. It works with any Firebox encryption level.
• Mobile User VPN – Uses Internet Protocol Security (IPSec). This type of
RUVPN is an optional feature of the WatchGuard package. It also requires that
the Firebox be approved and upgraded to strong or medium encryption level.
RUVPN requires configuration of both the Firebox and the end-user remote host
computers. This section describes how to configure a remote host for Remote User
For information on configuring a remote host for Mobile User VPN, see the Mobile
User VPN brochure provided with Mobile User VPN licenses. You can download a
copy from the LiveSecurity Service Web site.
Preparing the client computers
Every computer used as a Remote User VPN with PPTP remote host must first be
prepared with the following:
• Operating system software
• Device drivers
• Internet service provider account

Remote host operating system
The remote client must be running Windows and have the most recent MSDUN
(Microsoft Dial-Up Networking) upgrades installed and may need other extensions
and updates for proper configuration. Currently, Remote User VPN with PPTP
requires these upgrades according to platform:

Using Remote User PPTP
Using Remote User PPTP is a two-step process. First, the remote host establishes a
connection to the ISP. It then uses the VPN adapter to create a PPTP tunnel to the
Firebox.

page 142, double-click Connect with RUVPN.
Enter the remote client username and password.
These are assigned when you add the user to the pptp_users group. See “Using Remote User
Click Connect.
Running Remote User PPTP
When first starting the remote host (before connecting to the ISP or to the Firebox),
the user may be prompted for a name, password, and possibly even a domain. These
values are what Windows assumes the remote host uses to connect to the network
behind the Firebox. However, if Windows finds a discrepancy, it displays a login
prompt for the network with the name, password, and domain that would be used if
the remote host were at an office connecting directly to the LAN.
Remote User PPTP is usually set up such that the remote machines use
nonpublic IP addresses from the range used behind a Firebox. If the “Use
Default Gateway on Remote Network” parameter is enabled, and you try to
browse the Internet during a Remote User PPTP session, the Firebox
transmits the private address as the source IP address in the packet
header. Because the remote host was assigned an address from a private
address pool, a public Web site will not know how to route the return
traffic, and will ignore your request. Therefore, browse the Internet before
or after you are connected to the Firebox, but not during a Remote User
PPTP session.
If simultaneous access to the Internet and a private network is required,
contact WatchGuard Support for alternative solutions.

information and help with future troubleshooting.
