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.

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.

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.

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.

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.

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.

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 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.

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- site at www.linksys.com for more information.

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- site, www.linksys.com.

How will I be notified of new Gateway firmware upgrades? All Linksys firmware upgrades are posted on the Linksys website at www.linksys.com, where they can be downloaded for free. The Gateway’s firmware can be upgraded with TFTP programs.
