ADSL Gateway with Modem / Router / 4-Port Switch / Wireless-Ready
Chapter 1: Introduction
with Modem / Router / 4-Port Switch / Wireless-Ready
The Linksys ADSL Gateway
Thank you for choosing the Instant Broadband™ ADSL Gateway with Modem / Router / 4-
Port Switch / Wireless-Ready. This Gateway allows you to set up a network with your PCs
and share your Internet connection.
The Gateway does this by connecting to your ADSL line, and using the Gateway’s Ethernet
ports to connect your PCs; it’s like each PC is connected directly to the Internet. This way, you
have an Ethernet network where you have several PCs utilizing one Internet connection simul-
taneously. Plus, if you add a Linksys wireless PC Card, it can be used as an Access Point and
the Gateway can bridge your Ethernet network with your wireless PCs.
The PCs that you connect to the Gateway’s four LAN ports, when properly configured, cre-
ate a LAN, or Local Area Network. They are connected with an Ethernet cable plugged into
your computer’s Ethernet adapter at one end and into one of the Gateway's LAN ports (num-
bered from one to four) at the other end. The term “Ethernet” is used to refer to your network
accessories, such as cables and adapters, because Ethernet refers to the type of network that
you are setting up. Ethernet refers to the accessories that transfer computer data from 10Mbps
to 100Mbps (speeds used by network devices.)
The Gateway allows you to share yourADSL connection using a built-inADSL modem, and
can plug directly into yourADSL-enabled wall jack (DSL service line). The PCs that are con-
nected to the Gateway share this connection.

ADSL Gateway with Modem / Router / 4-Port Switch / Wireless-Ready
Think of the Gateway as a network device with two sides: the first side is made
up of your private Local Area Network (LAN) of PCs. The other, public side is
the Internet, or the Wide Area Network (WAN), outside of your home or office.
The Gateway’s firewall (NAT) protects your network of PCs so users on the
public, Internet side cannot “see” your PCs. This is how your LAN, or network,
remains private. The Gateway protects your network by inspecting the first
packet coming in through the WAN port before delivery to the final destination
on the LAN port. The Gateway inspects Internet port services like the web serv-
er, ftp server, or other Internet applications, and, if allowed, it will forward the
packet to the appropriate PC on the LAN side.
IP Addresses
What’s an IP Address?
IP stands for Internet Protocol. Every device on an IP-based network, including
PCs, print servers, and routers, requires an IP address to identify its “location,”
or address, on the network. This applies to both the WAN and LAN connections.
There are two ways of assigning an IP address to your network devices.
Figure 1-1
Package Contents
Static IP Addresses
• One ADSL Gateway with Modem / Router / 4-Port Switch / Wireless-Ready
• One Power Adapter
• One RJ-11 Phone Cable
• One User Guide
• One Fast Start and Registration Card (not shown)
A static IP address is a fixed IP address that you assign manually to a PC or
other device on the network. Since a static IP address remains valid until you
disable it, static IP addressing ensures that the device assigned it will always
have that same IP address until you change it. Static IP addresses are com-
monly used with network devices such as server PCs or print servers.
Minimum Requirements
When using the Gateway to share your ADSL Internet connection, contact your
ISP to find out if they have assigned a static IP address to your account. If so,
you will need that static IP address when configuring the Gateway. You can get
the information from your ISP.
• Network Adapter with Ethernet (UTP CAT 5) Cabling and TCP/IP Protocol
Installed per PC
• Internet Explorer 4.0 or Netscape Navigator 4.7 or Higher for Web-based
Configuration
• ADSL Connection and Activated Account
• Optional Wireless Network PC Card Model WPC11 for Wireless Connection
(sold separately)
Note: Since the Gateway is a device that connects two networks, it
needs two IP addresses—one for the LAN side, and one for the WAN
side. In this User Guide, you’ll see references to the “WAN IP
address” and the “LAN IP address.”
An Introduction to LANs and WANs
Since the Gateway has firewall security (NAT), the only IP address that
can be seen from the Internet for your network is the Gateway’s WAN
IP address.
Simply put, a router is a network device that connects two networks together.
In this instance, the Gateway connects your Local Area Network (LAN), or
the group of PCs in your home or office, to the Wide Area Network (WAN),
that is, the Internet. The Gateway processes and regulates the data that travels
between these two networks.
However, even this WAN IP address for the Gateway can be blocked,
so that the Gateway and network seem invisible to the Internet—see
the IP Filtering section in “Chapter 6: Using the Gateway’s Web-based
Utility.”

ADSL Gateway with Modem / Router / 4-Port Switch / Wireless-Ready
Dynamic IP Addresses
Network Setup Overview
A dynamic IP address is automatically assigned to a device on the network,
such as PCs and print servers. These IP addresses are called “dynamic”
because they are only temporarily assigned to the PC or device. After a certain
time period, they expire and may change. If a PC logs onto the network (or the
Internet) and its dynamic IP address has expired, the DHCP server will assign
it a new dynamic IP address.
This user guide covers the basic steps for setting up a network with a Gateway.
After going through the “Getting to Know the Gateway” chapter, most users
will only need to use the following chapters:
• Chapter 3: Connecting the Gateway
This chapter instructs you on how to connect the ADSL line to the Gateway
and connect the PC(s) to the Gateway.
For ADSL users, many ISPs may require you to log on with a user name and
password to gain access to the Internet. This is a dedicated, high-speed con-
nection type called Point to Point Protocol over Ethernet (PPPoE). PPPoE is
similar to a dial-up connection, but PPPoE does not dial a phone number when
establishing a connection. PPPoE also will provide the Gateway with a dynam-
ic IP address to establish a connection to the Internet. Point to Point Protocol
over ATM, or PPPoA, is a similar login method also used for some ADSL con-
nections.
• Chapter 4: Configuring the PCs
This chapter instructs you on how to configure your PC(s) for a DHCP con-
nection, if the network settings are not already set to DHCP.
• Chapter 5: Configuring the Gateway
This chapter explains how to configure the Gateway using your web browser
and the Gateway’s web-based utility. You will configure the Gateway using
the settings provided by your ISP.
DHCP (Dynamic Host Configuration Protocol) Servers
DHCP frees you from having to assign IP addresses manually every time a new
user is added to your network. PCs and other network devices using dynamic
IP addressing are assigned a new IP address by a DHCP server. The PC or net-
work device obtaining an IP address is called the DHCP client. By default, the
Gateway’s WAN setting is DHCP client.
When you’re finished with the basic steps, then you are ready to connect to the
Internet. After the PC(s) can access the Internet through the Gateway, you can
alter the Gateway’s settings further; for example, you can adjust security fea-
tures and other settings to enable online gaming, run Internet servers, config-
ure a wireless LAN (WPC11 required) and more!
A DHCP server can either be a designated PC on the network or another net-
work device, such as the Gateway. By default, a DHCP server (LAN side) is
enabled on the Gateway. If you already have a DHCP server running on your
network, you must disable one of the two DHCP servers. If you run more than
one DHCP server on your network, you will experience network errors, such as
conflicting IP addresses. To disable DHCP on the Gateway, see the DHCP sec-
tion in “Chapter 6: Using the Gateway’s Web-based Utility.”

Note: Even if you assign a static IP address to a PC, other PCs can
still use DHCP’s dynamic IP addressing, as long as the static IP
address is not within the DHCP range of the LAN IP Address.

Connecting Your Hardware and Booting Up
You will connect the Gateway to your ADSL line and to the computers in your
home or business.
Green. This LED flashes when there is activity across the
ADSL connection.
First, make sure that all the devices that you’ll be working with are powered
down, including your PCs and the Gateway.
1. Connect one end of the provided phone cable to the ADSL (RJ-11 phone)
port that is on the back of the Gateway.
Proceed to “Chapter 3: Connecting the Gateway.”
The Reset Button
Briefly pressing the Reset Button or rebooting the Gateway will refresh the
Gateway’s connections. If the Gateway locks up, simply press the Reset Button
or power it down for three to five seconds. Leaving the power off for too long
could result in the loss of network connections.
Pressing the Reset Button and holding it in for a few seconds will clear all of
the Gateway’s data and restore the factory defaults. This should be done only
if you are experiencing heavy routing problems, and only after you have
exhausted all of the other troubleshooting options. By resetting the Gateway,
you run the risk of creating conflicts between your PCs’ actual IP Addresses
and what the Gateway thinks their IP Addresses should be. You may be forced
to reboot each network PC.

Go to “Chapter 4: Configuring the PCs.”
If you are connecting more than four PCs to the Gateway, you will also need
to connect a hub or switch to the Gateway.
Note: A small device called a microfilter (not included) may be nec-
essary between each phone and wall jack to prevent interference.
Contact your ISP if you have any questions.
Note: If you have a Linksys wireless PC Card (WPC11), be sure to
fully insert it into the PC Card slot on the back of the Gateway before
turning on the power. You must have this card inserted in order to
use the Gateway's wireless features.
Note: The ADSL Gateway (with optional WPC11) is configured by
default to work out of the box with all Linksys Wireless Adapters. If
you have changed the defaults on your Linksys Wireless Adapters, or
are using other wireless adapters, you must temporarily change your
wireless adapter settings to: (SSID = linksys) in order to initially
access the Gateway wirelessly. After you have accessed the Gateway
with the default settings, you can change the Gateway settings to coin-
cide with your Network settings and reset your adapters.

Setup
The Setup screen is the first screen you see when you access the web-based
utility. If you have already installed and set up the Gateway, you have already
seen this screen and properly configured each of the values.
• Host Name & Domain Name These fields allow you to supply a host and
domain name for the Gateway. Some ISPs require these names as identifi-
cation. You may have to check with your ISP to see if your broadband
Internet service has been configured with a host and domain name. In most
cases, leaving these fields blank will work.
• Firmware Version This entry shows the version and date of the firmware
you are using. Future versions of the Gateway’s firmware will be posted and
• Current Time The Gateway will try to reach an Internet timeserver and dis-
play the current time in this location. If a timesaver cannot be reached, this
will show the time elapsed since the Gateway was powered on.
Figure 6-4
• Time Zone Set your local time zone in this field. If your region participates
in Daylight Savings Time (DST), check the box next to Daylight Savings
Time.
Note: The screen you see may vary depending on what kind of con-
nection mode you select.
• LAN IP Address and Subnet Mask The values for the Gateway’s IP
Address and Subnet Mask as seen on the internal LAN are shown here. The
default values are 192.168.1.1 for the Device IP Address and 255.255.255.0
for the Subnet Mask.
• Encapsulation The Gateway supports five encapsulation modes: RFC
1483 Bridged, RFC 1483 Routed, RFC 2364 PPPoA, RFC2516 PPPoE,
and Bridged Mode Only. These modes can be selected from the drop-down
menu next to the Encapsulation setting. Each Setup screen and available
features will differ depending on what kind of connection mode you select.
Each mode is described on the following pages.
• Virtual Circuit ID These fields consist of two items: VPI (Virtual Path
Identifier) and VCI (Virtual Channel Identifier). Your ISP will provide the
correct settings for these fields.
• Multiplexing The Gateway supports both VC and LLC multiplexing. Your
ISP will provide the correct selection for this setting.
VPI Enter the number provided by your ISP. The number will be in the
range of 0 to 255.
Note: After setup, you can test and see if the settings are correct by
successfully connecting to the Internet.
VCI Enter the number provided by your ISP. The number will be in the
range of 0 to 65535.

• Filtered Private Port Range To filter users by network port number, enter a
network port number or a range of network ports. Select the protocol for each
port number you want to filter, TCP or UDP. Enter the port numbers you want
to filter in the port numbers fields. Users connected to the Gateway will no
longer be able to access any port number listed there.
Forwarding
Important: This is an Advanced Function. No changes should be made
to this tab without a thorough understanding of network concepts.
Port Range Forwarding sets up public services on your network, such as web
servers, ftp servers, e-mail servers, or other specialized Internet applications.
(Specialized Internet applications are any applications that use Internet access
to perform functions such as videoconferencing or online gaming. Some
Internet applications may not require any forwarding.) When users send this
type of request to your network via the Internet, the Gateway will forward those
requests to the appropriate PC.
Private MAC Filter
• Click the Edit MAC Filter Setting button to filter users by entering their
physical addresses.
In the MAC Filter Setting screen, enter the MAC addresses that you want to
filter in the MAC address fields. The users with the filtered MAC addresses
will not be able to access the Internet. Click the Apply button and the
Continue button, before closing the window.
You may use this feature to establish a web server or FTP server for Internet
users to access. Be sure that you enter a valid IP address; you may need to
establish a static IP address with your ISP in order to properly run an Internet
server. For added security, Internet users will be able to communicate with the
server, but they will not actually be connected. The packets will be forwarded
through the Gateway instead. If you need to forward all ports to one PC, see the
“DMZ” section.
Block WAN Requests
• This feature is designed to protect users from Internet hackers and other
attacks. When enabled, the Gateway will ignore both unknown TCP and
ICMP packets from the WAN side. By enabling the Block WAN Request fea-
ture, you can prevent your network from being “pinged,” or detected, by other
Internet users. The Block WAN Request feature also reinforces your network
security by hiding your network ports. Both functions of the Block WAN
Request feature make it more difficult for outside users to work their way into
your network.
Remote Management
• This feature allows you to manage or configure the Gateway from a remote
location, via the Internet. To enable management through the WAN connec-
tion, click Enable, and use port 8080 on the remote PC you are using for
remote management.
Remote Upgrade
• This feature allows you to upgrade the Gateway’s firmware from a remote
location. To enable Remote Upgrade, click Enable.

To add a server using Port Range Forwarding:
Important: This is an Advanced Function. No changes should be made
to this tab without a thorough understanding of network concepts.
1. Enter the name of the application in the appropriate Customized
Applications field. This field is a description field only.
With Dynamic Routing you can enable the Gateway to automatically adjust to
physical changes in the network’s layout. The Gateway, using the RIP protocol,
determines the network packets’ route based on the fewest number of hops
between the source and the destination. The RIP protocol regularly broadcasts
routing information to other routers on the network. Select the RIP directions
and versions for the LAN and WAN sides.
2. Next to the name of the application, enter the range of the external port(s)
used by the server or Internet application in the Ext. Port column. Check
with the Internet application software documentation for more information.
3. Enter the IP address of the server that you want the Internet users to be
able to access. To find the IP address, go to “Appendix D: Finding the
MAC Address and IP Address for Your Ethernet Adapter.”
4. Configure as many entries as needed—the Gateway supports up to 11
ranges of ports. Click the Apply button and Continue button when you are
done.
To delete a server entry, enter 0 in the Ext. Port and IP Address fields.

Static Routing
Important: This is an Advanced Function. No changes should be made
to this tab without a thorough understanding of network concepts.
• RIP-1 Routing data will be sent in RIPv1 format.
• RIP-2B Routing data will be sent in RIPv2 format using subnet broadcast-
ing.
• RIP-2M Routing data will be sent in RIPv2 format using multicasting.
• N/A Routing data will not be sent.
If the Gateway is connected to more than one network, it may be necessary to
set up a static route between them. A static route is a pre-determined pathway
that network information must travel to reach a specific host or network. You
can use static routing to allow different IP domain users to access the Internet
through the Gateway.
Click the Show Routing Table button to open a chart displaying how data is
routed through your LAN.
The Gateway is also capable of dynamic routing (see the Dynamic Routing
tab). It is usually better to use dynamic routing because it allows the Gateway
to automatically adjust to physical changes in the network’s layout.
When finished making your changes on this tab, click the Apply button fol-
lowed by the Continue button to save these changes, or click the Cancel but-
ton to undo your changes. For further help on this tab, click the Help button.
To set up static routing, you should add routing entries in the Gateway’s table,
so the Gateway knows where to send all incoming packets.
Figure 6-22
To create a static route entry:
1. Select a Static Route Entry from the drop-down list. The Gateway sup-
ports up to eight static route entries.

DMZ Host
Important: This is an Advanced Function. No changes should be made
to this tab without a thorough understanding of network concepts.
Destination LAN IP: The Destination LAN IP is the address of the remote
network or host to which you want to assign a static route. Enter the IP
address of the host for which you wish to create a static route here. For a
standard Class C IP domain, the network address is the first three fields of
the Destination LAN IP, while the last field should be 0.
The DMZ Hosting function allows for a server attached to Port 4 of the
Gateway to be fully accessible from the Internet. The Gateway supports an
Advanced form of DMZ, allowing the system attached to Port 4 to be on a
secure subnet, separate from the computers attached to the other 3 ports.
Subnet Mask: The Subnet Mask (also known as the Network Mask) iden-

Make sure that you do NOT have a microfilter plugged in between the
Gateway and the wall jack. Verify that your ADSL account is active with
your ISP.
Appendix A: Troubleshooting
Common Problems and Solutions
5. I can’t browse through the Gateway.
This section provides possible solutions to problems regarding the Gateway’s
installation and operation. If your situation is described here, the problem
should be solved by applying the corresponding solution. If you can’t find an
• Check if both ends of the network cable and power adapter are properly
connected. Check if the status LEDs on the front panel are functioning
properly.
• If using Windows 95, 98 or Millennium, check the TCP/IP setup on the
client side. Run winipcfg by clicking on the Start button, selecting Run,
and typing winipcfg in the Run field. Press Enter. The PC should have
an IP address of 192.168.1.xxx (“xxx” is from 2 to 254.). The Subnet
Mask is 255.255.255.0; the default gateway IP should be the Gateway’s IP
Address, and check that the DNS is correct.
1. The Gateway is not working.
• Verify that the Power cord and other network cables are plugged in.
• Check the LAN and WAN LEDs on the Gateway’s front and verify that
they are lit appropriately.
• Check the settings on your PC.
• Check the Gateway’s settings.
• Check the same setup values in the Gateway’s Status page.
6. When I enter a URL or IP address, I get a time out error.
• Check to see if your other PCs work. If they do, verify that your PC’s IP
settings are correct (IP address, Subnet Mask, Default Gateway, and
DNS)
2. I can’t connect to the Gateway.
• Verify that the Gateway is properly installed; LAN connections are OK,
and it is powered ON.
• Make sure that your PC and the Gateway are on the same network seg-
ment. If you are not sure, initiate the DHCP function, and let the PC get
the IP address automatically.
• Make sure that your PC is using an IP address within the default range of
192.168.1.2 to 192.168.1.254 and thus compatible with the Gateway
default IP Address of 192.168.1.1
• Also, the Subnet Mask should be set to 255.255.255.0 to match the
Gateway. For the Gateway, you can check these settings by using Control
Panel-Network to check the Properties for the TCP/IP protocol.
• If the PCs are configured correctly, but still not working, check the
Gateway. Make sure that it is connected and ON. Connect to it and check
its settings. (If you cannot connect to it, check the LAN and power con-
nections.)
• If the Gateway is configured correctly, check your Internet connection to
see that it is working correctly.
• Manually configure the TCP/IP with a DNS address provided by your ISP.
7. I can’t obtain an IP address from my ADSL line.
• Verify that all of your cabling is properly connected and that all of the
Gateway’s ADSL and Link LEDs are correctly illuminated.
• Power down your Gateway for a few seconds. Turn it back on. After the
Gateway goes through its self-test, check to see if you now have an IP
address.
• Verify that the VPI/VCI and Encapsulation settings are correct in the
Setup page of the Web-based Utility. Go to the Setup section of the Web-
based Utility chapter for more information.
• If you are configured for PPPoE or PPPoA, verify that the username and
password are entered correctly in the Setup page of the Web-based Utility.
Go to the Setup section of the Web-based Utility chapter for more infor-
mation.
3. The Diag LED stays lit when it shouldn’t.
• The Diag LED lights up when the device is first powered up. Meantime,
the system will boot up itself and check for proper operation. After fin-
ishing the checking procedure, the LED turns off to show the system is
working fine. If the LED remains lit after this time, the device is not
working properly. Try to re-flash the firmware by assigning a static IP
address to the computer, and then upgrade the firmware again. If that
doesn’t help, contact your dealer for further inspection.
4. The ADSL Link LED will not go solid.
• Verify that the RJ-11 cable is firmly plugged into the ADSL jack of the
Gateway, with the other end plugged directly into the ADSL wall jack.

ADSL Gateway with Modem / Router / 4-Port Switch / Wireless-Ready
I set up an Unreal Tournament Server, but others on the LAN cannot join. What do
I need to do? If you have a dedicated Unreal Tournament server running, you
need to create a static IP for each of the LAN computers and forward ports
7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. You
can also use a port forwarding range of 7777 ~ 27900. If you want to use the
UT Server Admin, forward another port (8080 usually works well but is used
for remote admin. You may have to disable this.), and then in the
[UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (to
match the mapped port above) and ServerName to the IP assigned to the
Gateway from your ISP.
Frequently Asked Questions
What is the maximum number of IP addresses that the Gateway will support? The
Gateway will support up to 253 IP addresses.
Is IPSec Pass-Through supported by the Gateway?Yes, it is a built-in feature that
the Gateway automatically enables.
Does the Gateway support IPX or AppleTalk? No. TCP/IP is the only protocol
standard for the Internet and has become the global standard for communica-
tions. IPX, a NetWare communications protocol used only to route messages
from one node to another, and AppleTalk, a communications protocol used on
Apple and Macintosh networks, can be used for LAN to LAN connections,
but those protocols cannot connect from WAN to LAN.
Can multiple gamers on the LAN get on one game server and play simultaneously
with just one public IP address? It depends on which network game or what
kind of game server you are using. For example, Unreal Tournament supports
multi-login with one public IP.
What is Network Address Translation and what is it used for? Network Address
Translation (NAT) translates multiple IP addresses on the private LAN to one
public address that is sent out to the Internet. This adds a level of security
since the address of a PC connected to the private LAN is never transmitted
on the Internet. Furthermore, NAT allows the Gateway to be used with low
cost Internet accounts, when only one TCP/IP address is provided by the ISP.
The user may have many private addresses behind this single address provid-
ed by the ISP.
How do I get Half-Life:Team Fortress to work with the Gateway? The default client
port for Half-Life is 27005. The computers on your LAN need to have
“+clientport 2700x” added to the HL shortcut command line; the x would be
6, 7, 8, and on up. This lets multiple computers connect to the same server.
One problem: Version 1.0.1.6 won’t let multiple computers with the same CD
key connect at the same time, even if on the same LAN (not a problem with
1.0.1.3). As far as hosting games, the HL server does not need to be in the
DMZ. Just forward port 27015 to the local IP address of the server computer.
Does the Gateway support any operating system other than Windows 95, Windows
98, Windows 2000, Windows NT, or Windows XP? Yes, but Linksys does not, at
this time, provide technical support for setup, configuration or troubleshoot-
ing of any non-Windows operating systems.
The web page hangs; downloads are corrupt, or nothing but junk characters are
being displayed on the screen. What do I need to do? Force your Ethernet
adapter to 10Mbps or half duplex mode, and turn off the “Auto-negotiate”
feature of your Ethernet adapter as a temporary measure. (Please look at the
Network Control Panel in your Ethernet adapter’s Advanced Properties tab.)
Make sure that your proxy setting is disabled in the browser. Check our web-
Does the Gateway support ICQ send file? Yes, with the following fix: click ICQ
menu -> preference -> connections tab->, and check I am behind a fire-
wall or proxy. Then set the firewall time-out to 80 seconds in the firewall set-
ting. The Internet user can then send a file to a user behind the Gateway.
If all else fails in the installation, what can I do? Reset the Gateway by holding
down the reset button until the Diag LED fully turns on and off. Obtain and
flash the latest firmware release that is readily available on the Linksys web-
How do I get Napster to work with the Gateway? Napster is fully compatible with
the Gateway, but you must make sure that, during installation, you select “no
idea” when asked about your firewall selection. Set your proxy settings to
“No Proxy Server” in your File>Preferences.
How will I be notified of new Gateway firmware upgrades? All Linksys firmware
can be downloaded for free. The Gateway’s firmware can be upgraded with
TFTP programs.

Will the Gateway function in a Macintosh environment? Yes, but the Gateway’s
setup pages are accessible only through Internet Explorer v4.0 or Netscape
Navigator v4.0 or higher for Macintosh. NOTE: Linksys does not provide
technical support for Macintosh computers.
What are the Gateway’s advanced features? The Gateway’s advanced features

tion of the Gateway.
How do I get mIRC to work with the Gateway? Set port forwarding to 113 for the
computer on which you are using mIRC. If you are experiencing difficulty
after setting the port forwarding, try changing the Direct Client-to-Client
(DCC) settings to a range from 1024 to 1030 on the DCC option and
Forwarding page of the Web-based Setup Utility.
I am not able to access the Gateway’s web configuration screen. What can I do?
You may have to remove the proxy settings on your Internet browser, e.g.,
Netscape Navigator or Internet Explorer. Or remove the dial-up settings on
your browser. Check with your browser documentation.
What is DMZ? Demilitarized Zone (DMZ) allows one IP address (computer) to
be exposed to the Internet. Some applications require multiple TCP/IP ports
to be open. It is recommended that you set your computer with a static IP if
you want to use DMZ.
Can I guess my encapsulation type and VPI/VCI? These settings are dependent on
your telephone company, ADSL ISP, service level, and when your line was
installed. It is typically not something that can be guessed or found through
trial and error. It is best to contact your ISP to find these settings.
If DMZ is used, does the exposed user share the public IP with the Gateway? No.
Will this product work on an SDSL, IDSL or ISDN line? No, those types of lines are
not ADSL technologies. The BEFDSR41W will only work on ADSL lines
that support the T1.413i2, G.992.1 (G.dmt), or G.992.2 (G.lite) standards.
Does the Gateway pass PPTP packets or actively route PPTP sessions? The
Gateway allows PPTP packets to pass through.
If your questions are not addressed here, refer to the contact information
on the last page of this manual, or online at support.linksys.com.
Is the Gateway cross-platform compatible? Any platform that supports Ethernet
and TCP/IP is compatible with the Gateway.
Will the Gateway allow me to use my own public IPs and Domain, or do I have to
use the IPs provided by the Gateway? The Gateway allows for customization
of your public IPs and Domain.
How many ports can be simultaneously forwarded? Theoretically, the Gateway
can establish 520 sessions at the same time, but you can only forward 10
ranges of ports.
Does the Gateway replace a modem? Is there a DSL modem in the Gateway? Yes.
The Gateway has an integrated ADSL modem, so this product will replace
your current ADSL modem.

1. At the Wireless Screen, if you choose to enable WEP Encryption, select
Appendix B: Configuring
Mandatory under the WEP section.
2. Press the WEP Key Setting button to set the WEP Encryption type and
Wireless Security
level.
Note: WEP Encryption is an additional data security measure and
not essential for Gateway operation.
An acronym for Wired Equivalent Privacy, WEP is an encryption scheme used
to protect your wireless data communications. WEP uses a combination of 64-
bit or 128-bit keys to provide access control to your network and encryption
security for every data transmission. To decode a data transmission, each point
in a network must use an identical 64-bit or 128-bit key. Higher encryption lev-
els mean higher levels of security, but due to the complexity of the encryption,
they may mean decreased network performance.
You may also have heard the term “40-bit” used in conjunction with WEP
Encryption. This is simply another term for 64-bit WEP encryption. This level
of WEP encryption has been called 40-bit because it uses a 40-bit secret key
along with a 24-bit Initialization Vector (40 + 24 = 64). Wireless vendors may
use either name. Linksys uses the term “64-bit” when referring to this level of
encryption.

Encryption. Press the OK button to continue.
A 128-bit WEP encrypted wireless network will NOT communicate with a 64-
bit WEP encrypted wireless network. Therefore, make sure that all of your
wireless devices are using the same encryption level. All wireless devices com-
plying with the 802.11b standard will support 64-bit WEP.
In addition to enabling WEP, Linksys also recommends the following security
implementations:
• Changing the SSID from the default “linksys”
• Changing the WEP key regularly

Note: In order for WEP Encryption to be enabled, wireless functions must first
be enabled. Select Enable under the Wireless section before proceeding.

WEP Encryption key can be generated in one of two ways:
4. The following screen will appear, where you will choose your WEP
Encryption settings.
1. You may create an encryption key by using a Passphrase.
a. Enter a Passphrase, a user-defined password, into the Passphrase field.
The Passphrase can be a maximum of 31 letters, symbols, and numbers.
No spaces can be used.
b. Click the Generate button to create a key. The key will be 10 digits if
you chose 64-bit encryption, or 26 digits if you chose 128-bit encryp-
tion. This key will be used to encrypt and decrypt the data being sent
between the Gateway and your network’s wireless PCs.
The Key field may not display all digits. Using the mouse, click any-
where within the Key field. Move the cursor to the right to view the rest
of the Key. Make sure your write down the entire Key EXACTLY the
way it is displayed.
2. You may enter the encryption key manually.
Make a note of the Passphrase or Manual Key. You will need it for other wire-
less devices on the network, as the same WEP encryption key must be entered
in all wireless devices on the network.
Once you have chosen your key encryption method and entered either the
Passphrase or manual key, click the Apply button, and the encryption portion
of the setup is complete.

•
WEP (64Bit or 128B) Select the level of encryption from the drop-down
box. 128-bit WEP encryption is unique to Linksys and may conflict with
other vendors’ WEP encryption.
Note: In Windows XP, a 128-bit Key generated by the Gateway will be called a
"104 bits (26 digits)" key, and a 64-bit Key generated by the Gateway will be
called a “40 bits (10 digits)” key.
Note: In order to utilize WEP encryption, all points in your wireless network
must have WEP enabled and be set to the same Key Setting.
