Introduction to your BIPAC-7500G Router
Welcome to the Billion BIPAC-7500G Wireless Router. Your Billion router is an “all-in-one” unit,
combining an ADSL modem, ADSL router and Ethernet network switch, providing everything
you need to get the machines on your network connected to the Internet over your ADSL
broadband connection. With features such as an ADSL Quick-Start wizard and DHCP Server,
you can be online in no time at all and with a minimum of fuss and configuration, catering for
first-time users to the guru requiring advanced features and control over their Internet
connection and network.
Features
ADSL Multi-Mode Standard
Supports downstream transmission rates of up to 8Mbps and upstream transmission rates
of up to 1024Kbps. It also supports rate management that allows ADSL subscribers to
select an Internet access speed suiting their needs and budgets. It is compliant with Multi-
Mode standard (ANSI T1.413, Issue 2; G.dmt(G.992.1); G.lite(G992.2)). The Annex A and
B are supported in different H/W platforms.
Wireless Ethernet 802.11g
With built-in 802.11g access point for extending the communication media to WLAN while
providing the WEP and WPA for securing your wireless networks. The BIPAC-7500G has
included the first solution for turbo charging 802.11g systems called PRISM Nitro. It
provides up to 50% greater throughput performance in homogenous 802.11g networks
and enhanced protection mechanisms to significantly increase mixed-mode network
performance.
Fast Ethernet Switch
A 4-port 10/100Mbps fast Ethernet switch is built in with automatic switching between MDI
and MDI-X for 10Base-T and 100Base-TX ports. An Ethernet straight or cross-over cable
can be used directly for auto detection.
Multi-Protocol to Establish A Connection
Supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483
encapsulation over ATM (bridged or routed), PPP over Ethernet (RFC 2516), IPoA
(RFC1577) and PPTP-to-PPPoA relaying to establish a connection with the ISP. The
product also supports VC-based and LLC-based multiplexing.

immediately.
Universal Plug and Play (UPnP) and UPnP NAT Traversal
This protocol is used to enable simple and robust connectivity among stand-alone devices
and PCs from many different vendors. It makes network simple and affordable for users.
UPnP architecture leverages TCP/IP and the Web to enable seamless proximity
networking in addition to control and data transfer among networked devices. With this
feature enabled, users can now connect to Net meeting or MSN Messenger seamlessly.
Network Address Translation (NAT)
Allows multi-users to access outside resources such as the Internet simultaneously with
one IP address/one Internet access account. Many application layer gateway (ALG) are
supported such as web browser, ICQ, FTP, Telnet, E-mail, News, Net2phone, Ping,
NetMeeting, IP phone and others.
Firewall
Supports SOHO firewall with NAT technology, automatically detects and blocks Denial of
Service (DoS) attacks. URL blocking, packet filtering and SPI (Stateful Packet Inspection)
are also supported. The hacker’s attack will be recorded associated with timestamp in the
security logging area. More firewall functions will always be implemented through updated
firmware releases.
Domain Name System (DNS) relay
Provides an easy way to map the domain name (a friendly name for users such as
www.yahoo.com) and IP address. When a local machine sets its DNS server with this
router’s IP address, every DNS conversion request packet from the PC to this router will
be forwarded to the real DNS in the outside network.
Dynamic Domain Name System (DDNS)
The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname.
This dynamic IP address is the WAN IP address. For example, to use the service, you
must first apply for an account from a DDNS service like http://www.dyndns.org/. More
than 5 DDNS servers are supported.
Virtual Private Network (VPN)
Allows user to make a tunnel with a remote site directly to secure the data transmission
among the connection. User can use embedded PPTP client/server, IKE and IPSec which
are supported by this router to make a VPN connection or users can run the PPTP client in
PC and the router already provides IPSec and PPTP pass through function to establish a
VPN connection if the user likes to run the PPTP client in his local computer.
Virtual Server (“port forwarding”)
Users can specify some services to be visible from outside users. The router can detect
incoming service requests and forward either a single port or a range of ports to the
specific local computer to handle it. For example, a user can assign a PC in the LAN
acting as a WEB server inside and expose it to the outside network. Outside users can
browse inside web servers directly while it is protected by NAT. A DMZ host setting is also
provided to a local computer exposed to the outside network, Internet.
Rich Packet Filtering
Not only filters the packet based on IP address, but also based on Port numbers. It will
filter packets from and to the Internet, and also provides a higher level of security control.

In the WAN site, the DHCP client can get an IP address from the Internet Service Provider
(ISP) automatically. In the LAN site, the DHCP server can allocate a range of client IP
addresses and distribute them including IP address, subnet mask as well as DNS IP
address to local computers. It provides an easy way to manage the local IP network.
Static and RIP1/2 Routing
Supports an easy static routing table or RIP1/2 routing protocol to support routing
capability.
Simple Network Management Protocol (SNMP)

Cabling
One of the most common causes of problems is bad cabling or ADSL line(s). Make sure that all
connected devices are turned on. On the front of the product is a bank of LEDs. Verify that the
LAN Link and ADSL line LEDs are lit. If they are not, verify that you are using the proper cables.
Ensure that all other devices connected to the same telephone line as your Billion router (e.g.
telephones, fax machines, analogue modems) have a line filter connected between them and
the wall socket (unless you are using a Central Splitter or Central Filter installed by a qualified
and licensed electrician), and ensure that all line filters are correctly installed and the right way
around. Missing line filters or line filters installed the wrong way around can cause problems
with
your
ADSL
connection,
including
causing
frequent
disconnections.

Chapter 3: Basic Installation
The router can be configured with your web browser. A web browser is included as a standard
application in the following operating systems: Linux, Mac OS, Windows 98/NT/2000/XP/Me,
etc. The product provides a very easy and user-friendly interface for configuration.
PCs must have an Ethernet interface installed properly and be connected to the router either
directly or through an external repeater hub, and have TCP/IP installed and configured to obtain
an IP address through a DHCP server or a fixed IP address that must be in the same subnet as
the router. The default IP address of the router is 192.168.1.254 and the subnet mask is
255.255.255.0 (i.e. any attached PC must be in the same subnet, and have an IP address in the
range of 192.168.1.1 to 192.168.1.253). The best and easiest way is to configure the PC to get
an IP address automatically from the router using DHCP. If you encounter any problems
accessing the router’s web interface it may also be advisable to uninstall any kind of software
firewall on your PCs, as they can cause problems accessing the 192.168.1.254 IP address of
the router. Users should make their own decisions on how to best protect their network.
Please follow the steps below for your PC’s network environment installation. First of all, please
check your PC’s network components. The TCP/IP protocol stack and Ethernet network adapter
must be installed. If not, please refer to your Windows-related or other operating system
manuals.
Any TCP/IP capable workstation can be used to communicate with or
through the BIPAC-7500G. To configure other types of workstations,
please consult the manufacturer’s documentation.
Connecting your router
1. Connect the Router to a LAN (Local Area Network) and the ADSL/telephone network.
2. Power on the device.
3. Make sure the PWR, SYS and WLAN LEDs are lit steadily and that the relevant LAN LED is
lit.

WEP
WEP Encryption: To prevent unauthorized wireless stations from accessing data
transmitted over the network, the router offers highly secure data encryption, known as
WEP. If you require high security for transmissions, there are two alternatives to select
from: WEP 64 and WEP 128. WEP 128 will offer increased security over WEP 64.
Passphrase: This is used to generate WEP keys automatically based upon the input
string and a pre-defined algorithm in WEP64 or WEP128. You can input the same string in
both the AP and Client card settings to generate the same WEP keys. Please note that
you do not have to enter Key (0-3) as below when the Passphrase is enabled.
Default Used WEP Key: Select the encryption key ID, please refer to Key (0-3) below.
Key (0-3): Enter the key to encrypt wireless data. To allow encrypted data transmission,
the WEP Encryption Key values on all wireless stations must be the same as the router.
There are four keys for your selection. The input format is in HEX style, 5 and 13 HEX
codes are required for WEP64 and WEP128 respectively, the separator is “-“. For example,
using WEP64, 11-22-33-44-55 is a valid key, whilst 1122334455 is invalid.

Port Setting
This section allows you to configure the settings for the router’s Ethernet ports to solve
some of the compatibility problems that may be encountered while connecting to the
Internet, as well allowing users to tweak the performance of their network.
Port # Connection Type: Five options to choose from: Auto, 10M half-duplex, 10M full-
duplex, 100M half-duplex or 100M full-duplex. Sometimes, there are Ethernet compatibility
problems with legacy Ethernet devices, and you can configure different types to solve
compatibility issues. The default is Auto, which users should keep unless there are
specific problems with PCs not being able to access your LAN.
IPv4 TOS priority Control (Advanced users): TOS, Type of Services, is the 2nd octet of
an IP packet. Bits 6-7 of this octet are reserved and bit 0-2 are used to specify the priority
(precedence) of the packet, and bits 3-5 are specified the delay, throughput and reliability.
This feature uses bits 0-2 to classify the packet’s priority. If the packet is high priority, it will
flow first. Therefore, when this feature is enabled, the router’s Ethernet switch will check
the 2nd octet of each IP packet. If the value in the Precedence of TOS field matches the
checked values in the table (0 to 7), this packet will be treated as high priority.

DHCP Server
You can disable or enable the DHCP (Dynamic Host Configuration Protocol) server or
enable the router’s DHCP relay functions. The DHCP protocol allows your router to
dynamically assign IP addresses to PCs on your network if they are configured to obtain
IP addresses automatically.
To disable the router’s DHCP Server, check Disabled and click Next, then click Apply.
When the DHCP Server is disabled you will need to manually assign a fixed IP address to
each PCs on your network, and set the default gateway for each PCs to the IP address of
the router (by default this is 192.168.1.254).
To configure the router’s DHCP Server, check DHCP Server and click Next. You can then
configure parameters of the DHCP Server including the IP pool (starting IP address and
ending IP address to be allocated to PCs on your network), lease time for each assigned
IP address (the period of time the IP address assigned will be valid), DNS IP address and
the gateway IP address. These details are sent to the DHCP client (i.e. your PC) when it
requests an IP address from the DHCP server. Click Apply to enable this function. If you
check “Use Router as a DNS Server”, the ADSL Router will perform the domain name
lookup, find the IP address from the outside network automatically and forward it back to

DNS
A Domain Name System (DNS) contains a mapping table for domain name and IP
addresses. On the Internet, every host has a unique and user-friendly name (domain
name) such as www.billion.com and an IP address. An IP address is a 32-bit number in
the form of xxx.xxx.xxx.xxx, for example 192.168.1.254. You can think of an IP address as
a telephone number for devices on the Internet, and the DNS will allow you to find the
telephone number for any particular domain name. As an IP Address is hard to remember,
the DNS converts the friendly name into its equivalent IP Address.
You can obtain a Domain Name System (DNS) IP address automatically if your ISP has
provided it when you logon. Usually when you choose PPPoE or PPPoA as your WAN -
ISP protocol, the ISP will provide the DNS IP address automatically. You may leave the
configuration field blank. Alternatively, your ISP may provide you with an IP address of
their DNS. If this is the case, you must enter the DNS IP address.
If you choose one of the other three protocols ─ RFC1483 Routed/Bridged and IPoA
check with your ISP, it may provide you with an IP address for their DNS server. You must
enter the DNS IP address if you set the DNS of your PC to the LAN IP address of this

System
There are six items within the System section: Time Zone, Remote Access, Firmware
Upgrade, Backup/Restore, Restart and User Management.
Time Zone
The router does not have a real time clock on board; instead, it uses the Simple Network
Time Protocol (SNTP) to get the current time from an SNTP server outside your network.
Choose your local time zone, click Enable and click the Apply button. After a successful
connection to the Internet, the router will retrieve the correct local time from the SNTP
server you have specified. If you prefer to specify an SNTP server other than those in the
drop-down list, simply enter its IP address as shown above. Your ISP may provide an
SNTP server for you to use.
Resync Poll Interval (in minutes) is the periodic interval the router will wait before it re-
synchronizes the router’s time with that of the specified SNTP server. In order to avoid
unnecessarily increasing the load on your specified SNTP server you should keep the poll
interval as high as possible – at the absolute minimum every few hours or even days.

with different settings, knowing that you have a backup handy in the case of any mistakes.
It is advisable to backup your router’s settings before making any significant changes to
your router’s configuration.
Press Backup to select where on your local PC to save the settings file. You may also
change the name of the file when saving if you wish to keep multiple backups.
Press Browse to select a file from your PC to restore. You should only restore settings
files that have been generated by the Backup function, and that were created when using
the current version of the router’s firmware. Settings files saved to your PC should
not be manually edited in any way.
After selecting the settings file you wish to use, pressing Restore will load those settings
into the router.

User Management
In order to prevent unauthorized access to your router’s configuration interface, it requires
all users to login with a password. You can set up multiple user accounts, each with their
own password.
You are able to Edit existing users and Create new users who are able to access the
device’s configuration interface. Once you have clicked on Edit, you are shown the
following options:
You can change the user’s password, whether their account is active and Valid, as well
as add a comment to each user account. These options are the same when creating a
user account, with the exception that once created you cannot change the username. You
cannot delete the default admin account, however you can delete any other created
accounts by clicking Delete when editing the user.
You are strongly advised to change the password on the default “admin” account when
you receive your router, and any time you reset your configuration to Factory Defaults.

Firewall and Access Control
Your router includes a full SPI (Stateful Packet Inspection) firewall for controlling Internet access
from your LAN, as well as helping to prevent attacks from hackers. In addition to this, when
using NAT (Network Address Translation. Please see the WAN configuration section for more
details on NAT) the router acts as a “natural” Internet firewall, as all PCs on your LAN will use
private IP addresses that cannot be directly accessed from the Internet.
Firewall: Prevents access from outside your network. The router provides three levels of
security support:
NAT natural firewall: This masks LAN users’ IP addresses which are invisible to outside users
on the Internet, making it much more difficult for a hacker to target a machine on your network.
This natural firewall is on when NAT function is enabled.
When using Virtual Servers your PCs will be exposed to the degree
specified in your Virtual Server settings provided the ports specified are
opened in your firewall packet filter settings.
Firewall Security and Policy (General Settings): Inbound direction of Packet Filter rules to
prevent unauthorized computers or applications accessing your local network from the Internet.
Intrusion Detection: Enable Intrusion Detection to detect, prevent and log malicious attacks.
Access Control: Prevents access from PCs on your local network:
Firewall Security and Policy (General Settings): Outbound direction of Packet Filter rules to
prevent unauthorized computers or applications accessing the Internet.

General Settings
You can choose not to enable Firewall, to add all filter rules by yourself, or enable the
Firewall using preset filter rules and modify the port filter rules as required. The Packet
Filter is divided into two sections: Port Filters and Address Filters, used to filter packets
based-on Applications (Port) or IP addresses.
There are four options when you enable the Firewall, they are:
All blocked/User-defined: no pre-defined port or address filter rules by default,
meaning that all inbound (Internet to LAN) and outbound (LAN to Internet) packets
will be blocked. Users have to add their own filter rules for further access to the
Internet.
High/Medium/Low security level: the pre-defined port filter rules for High, Medium
and Low security are displayed in Port Filters of Packet Filter.
Select either High, Medium or Low security level to enable the Firewall. The only
difference between these three security levels is the preset port filter rules in the Packet
Filter. Firewall functionality is the same for all levels; it is only the list of preset port filters
that changes between each setting.
If you choose of the preset security levels and then add custom filters, you may
temporarily disable the firewall and recover your custom filter settings by re-selecting the
same security level.
The “Block WAN Request” is a stand-alone function and not relate to whether security
enable or disable. Mostly it is for preventing any scan tools from WAN site by hacker.
Any remote user who is attempting to perform this action may result in
blocking all the accesses to configure and manage of the device from the
Internet.

Address Filters
Address Filters are used to block traffic to/from particular IP addresses. They can be used
to block IP addresses either on the Internet or on your local network. There are no pre-
defined address filter rules; you can add the filter rules to meet your requirements. There
are two kinds of address filters, one is inbound, and the other is outbound. The rules can
be set to prevent unauthorized users (hosts or network) to access the Internet from LAN
(outbound) and/or access LAN from the Internet (inbound).
Host IP Address: This is the IP address you wish to block access to or from.
Host Subnet Mask: This is the subnet mask for the IP address range you wish to block.
Direction: Whether you want to block access to the Internet (“outbound”), from the
Internet (“inbound”) or both to and from the Internet (“both”).
Tip: To block access to/from a single IP address, enter that IP address as the Host IP
Address and use a Host Subnet Mask of “255.255.255.255”.

on your LAN
The pre-defined port filter rule for HTTP (TCP port 80) is the same no matter whether the
firewall is set to a high, medium or low security level. To setup a web server located on the local
network when the firewall is enabled, you have to configure the Port Filters setting for HTTP.
As you can see from the diagram below, when the firewall is enabled with one of the three
presets (Low/Medium/High), inbound HTTP access is not allowed.

Intrusion Detection
The router’s Intrusion Detection System (IDS) is used to detect hacker attacks and
intrusion attempts from the Internet. If the IDS function of the firewall is enabled, inbound
packets are filtered and blocked depending on whether they are detected as possible
hacker attacks, intrusion attempts or other connections that the router determines to be
suspicious.
Blacklist: If the router detects a possible attack, the source IP or destination IP address
will be added to the Blacklist. Any further attempts using this IP address will be blocked for
the time period specified as the Block Duration. The default setting for this function is
false (disabled). Some attack types are denied immediately without using the Blacklist
function, such as Land attack and Echo/CharGen scan.
Block Duration:
DoS Attack Block Duration: This is the duration for blocking hosts that attempt a
possible Denial of Service (DoS) attack. Possible DoS attacks this attempts to block
include Ascend Kill and WinNuke. Default value is 1800 seconds.
Scan Attack Block Duration: This is the duration for blocking hosts that attempt a
possible Scan attack. Scan attack types include X’mas scan, IMAP SYN/FIN scan
and similar attempts. Default value is 86400 seconds.
Victim Protection Block Duration: This is the duration for blocking Smurf attacks.
Default value is 600 seconds.
Victim Protection: If enabled, IDS will block Smurf attack attempts. Default is false.
Max TCP Open Handshaking Count: This is a threshold value to decide whether a SYN
Flood attempt is occurring or not. Default value is 100 TCP SYN per seconds.

Max ICMP Count: This is a threshold to decide whether an ICMP flood is occurring or not.
Default value is 100 ICMP packets per seconds except ICMP Echo Requests (PING).
For SYN Flood, ICMP Echo Storm and ICMP flood, IDS will just warn the user in the Event
Log. It cannot protect against such attacks.

accessing particular websites by their URL. There are no pre-defined URL filter rules; you
can add filter rules to meet your requirements.
Enable/Disable: To enable or disable URL Filter feature.
Always Block: Select to always check the URL filter rules (i.e. at all hours of the day).
Block from: Specify the time period to check the URL filter rules (e.g. during work hours).
Keywords Filtering: Allows blocking by specific keywords within a particular URL rather
than having to specify a complete URL (e.g. to block any image called “advertisement.gif”).
When enabled, your specified keywords list will be checked to see if any keywords are
present in URLs accessed to determine if the connection attempt should be blocked.
Please note that the URL filter blocks web browser (HTTP) connection attempts using port
80 only.
For example, if the URL is http://www.billion.com.tw/abcde.html, it will be dropped as the
keyword “abcde” occurs in the URL.

Domains Filtering: This function checks the domain name in URLs accessed against
your list of domains to block or allow. If it is matched, the URL request will be sent (Trusted)
or dropped (Forbidden). The checking procedure is:
1. Check the domain in the URL to determine if it is in the trusted list. If yes, the
connection attempt is sent to the remote web server.
2. If not, check if it is listed in the forbidden list, and if present then the connection
attempt is dropped..
3. If the packet does not match either of the above two items, it is sent to the remote web
server.
4. Please be note that the domain only should be specified, not the full URL. For
example to block traffic to www.sex.com, enter “sex” or “sex.com” instead of
“www.sex.com”. In the example below, the URL request for www.billion.com.tw will be
sent to the remote web server because it is listed in the trusted list, whilst the URL
request for www.sex or www.sex.com will be dropped, because billion.com is in the
forbidden list.

128 characters. Both sides should use the same key. IKE is used to establish a shared
security policy and authenticated keys for services (such as IPSec) that require a key.
Before any IPSec traffic can be passed, each router must be able to verify the identity of
its peer. This can be done by manually entering the pre-shared key into both sides (router

Advanced Option
Click Advanced Option to change the following settings:
SA Lifetime: Specify the number of minutes that a Security Association (SA) will stay
active before new encryption and authentication key will be exchanged. There are two
kinds of SAs, IKE and IPSec. IKE negotiates and establishes SA on behalf of IPSec, an
IKE SA is used by IKE.
Phase 1 (IKE): To issue an initial connection request for a new VPN tunnel. The range can
be from 5 to 15,000 minutes, and the default is 240 minutes.
Phase 2 (IPSec): To negotiate and establish secure authentication. The range can be
from 5 to 15,000 minutes, and the default is 60 minutes.
A short SA time increases security by forcing the two parties to update the keys. However,
every time the VPN tunnel re-negotiates, access through the tunnel will be temporarily
disconnected.

Authentication Protocol) or PAP (Password Authentication Protocol) if you know which
type the server is using (when acting as a client), or else the authentication type you want
clients connecting to you to use (when acting as a server). When using PAP, the password
is sent unencrypted, whilst CHAP encrypts the password before sending, and also allows
for challenges at different periods to ensure that the client has not been replaced by an
intruder.
Idle Time: Auto-disconnect the VPN connection when there is no activity on the

Virtual Server (“Port Forwarding”)
In TCP/IP and UDP networks a port is a 16-bit number used to identify which application
program (usually a server) incoming connections should be delivered to. Some ports have
numbers that are pre-assigned to them by the IANA (the Internet Assigned Numbers Authority),
and these are referred to as “well-known ports”. Servers follow the well-known port assignments
so clients can locate them.
If you wish to run a server on your network that can be accessed from the WAN (i.e. from other
machines on the Internet that are outside your local network), or any application that can accept
incoming connections (e.g. Peer-to-peer/P2P software such as instant messaging applications
and P2P file-sharing applications) and are using NAT (Network Address Translation), then you
will usually need to configure your router to forward these incoming connection attempts using
specific ports to the PC on your network running the application. You will also need to use port
forwarding if you want to host an online game server.
The reason for this is that when using NAT, your publicly accessible IP address will be used by
and point to your router, which then needs to deliver all traffic to the private IP addresses used
by your PCs. Please see the WAN configuration section of this manual for more information on
NAT.
The Internet Assigned Numbers Authority (IANA) is the central coordinator for the assignment of
unique parameter values for Internet protocols. Port numbers range from 0 to 65535, but only
ports numbers 0 to 1023 are reserved for privileged services and are designated as “well-known
ports”. The registered ports are numbered from 1024 through 49151. The remaining ports,
referred to as dynamic ports or private ports, are numbered from 49152 through 65535.
Examples of well-known and registered port numbers are shown in Table 4, for further
information, please see IANA’s website at: http://www.iana.org/assignments/port-numbers
For help on determining which private port numbers are used by common applications on this
list, please see the FAQs (Frequently Asked Questions) at: http://www.billion.com

Because NAT can act as a “natural” Internet firewall, your router protects your network from
being accessed by outside users when using NAT, as all incoming connection attempts will point
to your router unless you specifically create Virtual Server entries to forward those ports to a PC
on your network. When your router needs to allow outside users to access internal servers, e.g.
a web server, FTP server, Email server or game server, the router can act as a “virtual server”.
You can set up a local server with a specific port number for the service to use, e.g. web/HTTP
(port 80), FTP (port 21), Telnet (port 23), SMTP (port 25), or POP3 (port 110), When an
incoming access request to the router for a specified port is received, it will be forwarded to the
corresponding internal server.
For example, if you set the port number 80 (Web/HTTP) to be mapped to the IP Address
192.168.1.2, then all incoming HTTP requests from outside users will be forwarded to the local
server (PC) with the IP address of 192.168.1.2. If the port is not listed as a predefined
application, you need to add it manually.
In addition to specifying the port number to be used, you will also need to specify the protocol
used. The protocol used is determined by the particular application. Most applications will use

TCP or UDP, however you can specify other protocols using the drop-down Protocol menu.
Setting the protocol to “all” will cause all incoming connection attempts using all protocols on all
port numbers to be forwarded to the specified IP address.
DMZ: The DMZ Host is a local computer exposed to the Internet. When setting a particular
internal IP address as the DMZ Host, all incoming packets will be checked by the Firewall and
NAT algorithms, then passed to the DMZ host when a packet received does not use a port
number used by any other Virtual Server entries.
Using port forwarding does have security implications, as outside users will
be able to connect to PCs on your network. For this reason you are
advised to use specific Virtual Server entries just for the ports your
application requires instead of simply using DMZ or create a Virtual Server
entry for “All” protocols, as doing so will result in all connection attempts to
your public IP address will access the PC specified.
If you have disabled the NAT option in the WAN-ISP section, the Virtual
Server function will hence be invalid.
If the DHCP server option is enabled, you have to be very careful in
assigning the IP addresses of the virtual servers in order to avoid conflicts.
The easiest way of configuring Virtual Servers is to manually assign static
IP address to each virtual server PC, with an address that does not fall into
the range of IP addresses that are to be issued by the DHCP server. You
can configure the virtual server IP address manually, but it must still be in
the same subnet as the router.

Dynamic DNS
The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname,
allowing users whose ISP does not assign them a static IP address to use a domain name.
This is especially useful for hosting servers via your ADSL connection, so that anyone
wishing to connect to you may use your domain name, rather than having to use your
dynamic IP address, which changes from time to time. This dynamic IP address is the
WAN IP address of the router, which is assigned to you by your ISP.
You will first need to register and establish an account with the Dynamic DNS provider
using their website, for example http://www.dyndns.org/
There are more than 5 DDNS services supported.
ꢁDisable: Check to disable the Dynamic DNS function.
ꢁEnable: Check to enable the Dynamic DNS function. The following fields will be
activated and required:
Dynamic DNS Server: Select the DDNS service you have established an account with.
Domain Name, Username and Password: Enter your registered domain name and your
username and password for this service.
Period: Set the time period between updates, for the Router to exchange information with
the DDNS server. In addition to updating periodically as per your settings, the router will
perform an update when your dynamic IP address changes.
Via WAN Interface: Decide which WAN interface you want to use for sending DDNS
request.

Check Emails
This function allows you to have the router check your POP3 mailbox for new Email
messages. The Mail LED on your router will light when it detects new messages waiting
for download. You may also view the status of this function using the Status – Email
Checking section of the web interface, which also provides details on the number of new
messages waiting. See the Status section of this manual for more information.
ꢁDisable: Check to disable the router’s Email checking function.
ꢁEnable: Check to enable the routers Emailing checking function. The following fields
will be activated and required:

(ISP) or network administrator will be able to supply you with this.
Interval: Enter the value in minutes between periodic mail checks.
Automatically dial-out for checking emails: When the function is enabled, your ADSL
router will connect to your ISP automatically to check emails if your Internet connection
dropped. Please be careful when using this feature if your ADSL service is charged by
time online.

Device Management
The Device Management advanced configuration settings allow you to control your
router’s security options and device monitoring features.
Embedded Web Server:
HTTP Port: This is the port number the router’s embedded web server (for web-based
configuration) will use. The default value is the standard HTTP port, 80. Users may specify
an alternative if, for example, they are running a web server on a PC within their LAN.
Management IP Address: You may specify an IP address allowed to logon and access
the router’s web server. Setting the IP address to 0.0.0.0 will disable IP address
restrictions, allowing users to login from any IP address.
Expire to auto-logout: Specify a time frame for the system to auto-logout the user’s
configuration session.
For Example: User A changes HTTP port number to 100, specifies their own IP address
of 192.168.1.55, and sets the logout time to be 100 seconds. The router will only allow
User A access from the IP address 192.168.1.55 to logon to the Web GUI by typing:
http://192.168.1.254:100 in their web browser. After 100 seconds, the device will
automatically logout User A.

Universal Plug and Play (UPnP):
UPnP offers peer-to-peer network connectivity for PCs and other network devices, along
with control and data transfer between devices. UPnP offers many advantages for users
running NAT routers through UPnP NAT Traversal, and on supported systems makes
tasks such as port forwarding much easier by letting the application control the required
settings, removing the need for the user to control advanced configuration of their device.
Both the user’s Operating System and the relevant application must support UPnP in
addition to the router. Windows XP and Windows Me natively support UPnP (when the
component is installed), and Windows 98 users may install the Internet Connection
Sharing client from Windows XP in order to support UPnP. Windows 2000 does not
support UPnP.
ꢁDisable: Check to disable the router’s UPnP functionality.
ꢁEnable: Check to enable the router’s UPnP functionality.
UPnP Port: Its default setting is 2800. It is highly recommended for users to use this port
value. If this value conflicts with other ports already being used you may wish to change
the port.
SNMP Access Control (Software on a PC within the LAN is required in order to utilize this
function) – Simple Network Management Protocol.
SNMP V1 and V2:
Read Community: Specify a name to be identified as the Read Community, and an IP
address. This community string will be checked against the string entered in the
configuration file. Once the string name is matched, user obtains this IP address will be
able to view the data.
Write Community: Specify a name to be identified as the Write Community, and an IP
address. This community string will be checked against the string entered in the
configuration file. Once the string name is matched, users from this IP address will be able
to view and modify the data.
Trap Community: Specify a name to be identified as the Trap Community, and an IP
address. This community string will be checked against the string entered in the
configuration file. Once the string name is matched, users from this IP address will be
sent SNMP Traps.
SNMP V3:
Specify a name and password for authentication. And define the access right from
identified IP address. Once the authentication has succeeded, users from this IP address
will be able to view and modify the data.

SNMP Version: SNMPv2c and SNMPv3
SNMPv2c is the combination of the enhanced protocol features of SNMPv2 without the
SNMPv2 security. The "c" comes from the fact that SNMPv2c uses the SNMPv1
community string paradigm for "security", but is widely accepted as the SNMPv2 standard.
SNMPv3 is a strong authentication mechanism, authorization with fine granularity for
remote monitoring.
Traps supported: Cold Start, Authentication Failure.

Logout
To exit the router’s web interface, choose Logout. Please ensure that you have saved the
configuration settings before you logout.
Be aware that the router is restricted to only one PC accessing the configuration web pages at a
time. Once a PC has logged into the web interface, other PCs cannot get access until the
current PC has logged out of the web interface. If the previous PC forgets to logout, the second
PC can access the page after a user-defined period, by default 3 minutes. You can modify this
value using the Advanced – Device Management section of the web interface. Please see the
