3.

Enter the External Port range of the service you are using. For example, if you want to host Unreal

Tournament (UT), you would enter the range 7777 to 27900.

4.

Check the protocol you will be using, TCP and/or UDP.

5.

Enter the IP address of the PC or network device that you want the port server to go to. For example,

if the web server’s Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field

provided. Check “Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter” for

details on getting an IP address.

I can’t get the Internet game, server, or application to work.

If you are having difficulties getting any Internet game, server, or application to function properly, consider

exposing one PC to the Internet using DeMilitarized Zone (DMZ) hosting. This option is available when an

application requires too many ports or when you are not sure which port services to use. Make sure you

disable all the forwarding entries if you want to successfully use DMZ hosting, since forwarding has priority

over DMZ hosting. (In other words, data that enters the Router will be checked first by the forwarding

settings. If the port number that the data enters from does not have port forwarding, then the Router will send

the data to whichever PC or network device you set for DMZ hosting.)

•

Follow these steps to set DMZ hosting:

1.

Access the Router’s web-based utility by going to http://192.168.1.1 or the IP address of the Router.

Go to the Applications & Gaming => Port Forwarding tab.

2.

Disable or remove the entries you have entered for forwarding.

Keep this information in case you

want to use it at a later time.

3.

Go to the Applications & Gaming => DMZ tab.

4.

Select Enable next to DMZ. In the DMZ Host IP Address field, enter the IP address of the computer you

want exposed to the Internet.

This will bypass the NAT technology for that computer. Please refer to

“Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on

getting an IP address.

•

Once completed with the configuration, click the

Apply

button.

10.I forgot my password, or the password prompt always appears when I am saving settings to the

field to confirm the password.

3.

Click the

Save Settings

button.

11.I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window.

If you have proxy settings, you need to disable these on your computer. Because the Router is the gateway for

the Internet connection, the computer does not need any proxy settings to gain access.

Please follow these

directions to verify that you do not have any proxy settings and that the browser you use is set to connect

directly to the LAN.

•

If the firmware upgrade failed, use the TFTP program (it was downloaded along with the firmware). Open

the pdf that was downloaded along with the firmware and TFTP program, and follow the pdf’s

instructions.

•

Set a static IP address on the PC; refer to “Problem #1, I need to set a static IP address.” Use the following

IP address settings for the computer you are using:

IP Address: 192.168.1.50

•

Perform the upgrade using the TFTP program or the Router’s web-based utility through its System tab.

15.My DSL service’s PPPoE is always disconnecting.

PPPoE is not actually a dedicated or always-on connection.

The DSL ISP can disconnect the service after a

period of inactivity, just like a normal phone dial-up connection to the Internet.

•

There is a setup option to “keep alive” the connection.

This may not always work, so you may need to re-

establish connection periodically.

1.

To connect to the Router, go to the web browser, and enter http://192.168.1.1 or the IP address of the

Router.

17.The Power LED keeps flashing.

The Power LED flashes when the device is first powered up. Meantime, the system will boot up itself and

check for proper operation. After finishing the checking procedure, the LED stays solid to show that the

system is working fine. If the LED keeps flashing after this time, the device is not working properly. Try to

flash the firmware by assigning a static IP address to the computer, and then upgrade the firmware. Try using

the following settings, IP Address: 192.168.1.50 and Subnet Mask: 255.255.255.0.

18.When I enter a URL or IP address, I get a time-out error or am prompted to retry.

•

Check if other PCs work. If they do, ensure that your workstation’s IP settings are correct (IP Address,

Subnet Mask, Default Gateway, and DNS). Restart the computer that is having a problem.

•

If the PCs are configured correctly, but still not working, check the

Router. Ensure that it is connected and

powered on. Connect to it and check its settings. (If you cannot connect to it, check the LAN and power

connections.)

•

If the Router is configured correctly, check your Internet connection (DSL/cable modem, etc.) to see if it is

working correctly. You can remove the Router to verify a direct connection.

•

Manually configure the TCP/IP settings with a DNS address provided by your ISP.

Frequently Asked Questions

What is the maximum number of IP addresses that the Router will support?

The Router will support up to 253 IP addresses.

Is IPSec Pass-Through supported by the Router?

Yes, it is a built-in feature that the Router automatically enables.

Where is the Router installed on the network?

In a typical environment, the Router is installed between the cable/DSL modem and the LAN.

Plug the Router into

the cable/DSL modem’s Ethernet port.

Does the Router support IPX or AppleTalk?

No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications.

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 the Internet to a LAN.

Frequently Asked Questions

Wireless-B Broadband Router

Does the Internet connection of the Router support 100Mbps Ethernet?

The Router’s current hardware design supports up to 100Mbps Ethernet on its Internet port; however, the Internet

connection speed will vary depending on the speed of your broadband connection. The Router also supports

100Mbps over the auto-sensing Fast Ethernet 10/100 switch on the LAN side of the Router.

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 Router to be used with low cost Internet

accounts, such as DSL or cable modems, when only one TCP/IP address is provided by the ISP. The user may

have many private addresses behind this single address provided by the ISP.

Does the Router support any operating system other than Windows 98, Windows Millennium, Windows

2000, or Windows XP?

Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of

any non-Windows operating systems.

Does the Router support ICQ send file?

Yes, with the following fix: click ICQ menu -> preference -> connections tab->, and check I am behind a firewall

or proxy. Then set the firewall time-out to 80 seconds in the firewall setting. The Internet user can then send a file

to a user behind the 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 ~ 27900. If you want to use the UT Server Admin, forward another port.

(Port 8080 usually works well but is used for remote admin. You may have to disable this.) 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
