information on what port services to use is to go to the website of the online game or application you want to

use. Follow these steps to set up online game hosting or use a certain Internet application:

A.

Access the Phone Adapter’s Web-based Utility by going to

or the IP address of the

Phone Adapter. Go to the

Router

=>

Application

tab.

B.

Select

yes

from the

Enable

drop-down menu.

C.

Enter any name you want to use for the service.

D.

Enter the port range of the service you are using. For example, if you have a web server, you would enter

the range 80 (in the

Starting Port

field) to 80 (in the

Ending Port

field).

E.

Select the protocol you will be using,

TCP

or

UDP

, or select

Both

.

F.

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 192.168.0.100, you would enter 100 in the field

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

details on getting an IP address.

Common Problems and Solutions

9.

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 Phone Adapter will be checked first by the forwarding

settings. If the port number that the data enters from does not have port forwarding, then the Phone Adapter

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

Follow these steps to set

DMZ hosting:

A.

Access the Phone Adapter’s Web-based Utility by going to

or the IP address of the

Phone Adapter. Go to the

Router

=>

Application

tab.

B.

Disable or remove the entries you have entered for forwarding. Keep this information in case you want to

use it at a later time.

C.

Select

yes

from the

Enable DMZ

drop-down menu.

D.

Enter the Ethernet adapter’s IP address of the computer you want exposed to the Internet.

This will

bypass the NAT security for that computer. Please refer to “Appendix B: 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

Submit All Changes

button.

10. 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 Phone Adapter 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.

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

Go through this checklist until your problem is solved:

•

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 Phone Adapter. 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 Phone Adapter is configured correctly, check your Internet connection (DSL/cable modem, etc.) to

see if it is working correctly. You can remove the Phone Adapter to verify a direct connection.

•

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

•

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

Explorer, click

Tools

,

Internet Options

, and then the

Connection

tab. Make sure that Internet Explorer

is set to

Appendix A: Troubleshooting

Frequently Asked Questions

Frequently Asked Questions

Can I make Internet phone calls if my Internet connection is down?

No. When you make Internet phone calls, your high-speed Internet connection must be active.

Can I make calls while I’m browsing the Internet?

Yes. You can make calls while browsing the Internet. However, your web browsing may affect the quality of your

Internet calls, depending on the amount of upstream data traffic passing through your Internet connection.

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

The Phone Adapter will support up to 253 IP addresses.

Where is the Phone Adapter installed on the network?

In a typical environment, the Phone Adapter is installed between the cable/DSL modem and the local area

network (LAN). Plug the Phone Adapter into the cable/DSL modem’s Ethernet port.

Does the Phone Adapter 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 the 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 Phone Adapter 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.

Appendix A: Troubleshooting

Frequently Asked Questions

Does the Phone Adapter support any operating system other than Windows 98, Millennium, 2000,

or 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 Phone Adapter 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 Phone Adapter.

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 Phone Adapter 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 Phone Adapter?

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
