Frequently Asked Questions

Broadband Router

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 to 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 Router from your ISP.

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.

How do I get

Half-Life: Team Fortress

to work with the Router?

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.

How can I block corrupted FTP downloads?

If you are experiencing corrupted files when you download a file with your FTP client, try using another FTP

program.

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 website at

www.linksys.com

for more information.

If all else fails in the installation, what can I do?

Reset the Router by holding down the Reset button for ten seconds. Reset your cable or DSL modem by powering

the unit off and then on.

Obtain and flash the latest firmware release that is readily available on the Linksys

website,

www.linksys.com

.

How can I be notified of new Router firmware upgrades?

All Linksys firmware upgrades are posted on the Linksys website at

www.linksys.com

, where they can be

downloaded for free.

The Router’s firmware can be upgraded using the Web-based Utility. If the Router’s Internet

connection is working well, there is no need to download a newer firmware version, unless that version contains

new features that you would like to use.

Downloading a more current version of Router firmware will not

enhance the quality or speed of your Internet connection, and may disrupt your current connection stability.

Will the Router function in a Macintosh environment?

Yes, but the Router’s setup pages are accessible only through Internet Explorer 5.0 or Netscape Navigator 5.0 or

higher for Macintosh.

I am not able to get the web configuration screen for the Router. 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, and make

sure that your browser is set to connect directly and that any dial-up is disabled. Make sure that your browser is

set to connect directly and that any dial-up is disabled. For Internet Explorer, click

.

What is DMZ Hosting?

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 Hosting. To get the LAN IP address, see “Appendix C: Finding the MAC Address and IP Address

for Your Ethernet Adapter.”

If DMZ Hosting is used, does the exposed user share the public IP with the Router?

No.

Does the Router pass PPTP packets or actively route PPTP sessions?

The Router allows PPTP packets to pass through.

Is the Router cross-platform compatible?

Any platform that supports Ethernet and TCP/IP is compatible with the Router.

How many ports can be simultaneously forwarded?

Theoretically, the Router can establish 4,000 sessions at the same time, but you can only forward 30 ranges of

ports.

Does the Router replace a modem? Is there a cable or DSL modem in the Router?

No, this version of the Router must work in conjunction with a cable or DSL modem.

Which modems are compatible with the Router?

The Router is compatible with virtually any cable or DSL modem that supports Ethernet.

Appendix C: Finding the MAC Address and IP Address for

Your Ethernet Adapter

This section describes how to find the MAC address for your computer’s Ethernet adapter so you can use the MAC

address cloning feature of the Router. You can also find the IP address of your computer’s Ethernet adapter. This

IP address is used for the Router’s filtering, forwarding, and/or DMZ features. Follow the steps in this appendix to

find the adapter’s MAC or IP address in Windows 98, Me, 2000, or XP.

Windows 98 or Me Instructions

1.

Click

Start

and

Run

. In the

Open

field, enter

winipcfg

. Then press the

Enter

key or the

OK

button.

2.

When the

IP Configuration

screen appears, select the Ethernet adapter you have connected to the Router via a

CAT 5 Ethernet network cable.

3.

Write down the Adapter Address as shown on your computer screen. This is the MAC address for your

Ethernet adapter and is shown as a series of numbers and letters.

The MAC address/Adapter Address is what you will use for MAC address cloning or MAC filtering.

The example shows the Ethernet adapter’s IP address as 192.168.1.100. Your computer may show something

different.

Windows 2000 or XP Instructions

1.

Click

Start

and

Run

. In the

Open

field, enter
