Wireless-G Broadband Router with 2 Phone Ports
provided. Check "Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter" for
details on getting an IP address.
6. Check the Enable option for the port services you want to use. Consider the example below:
Application Start and End
UT 7777 to 27900
Halflife 27015 to 27015
PC Anywhere 5631 to 5631
VPN IPSEC 500 to 500
When you have completed the configuration, click the Save Settings button.
10. 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.
5. Once completed with the configuration, click the Save Settings button.
