7. I need to set up online game hosting or use other Internet applications.
If you want to play online games or use Internet applications, most will work without doing any port
forwarding or DMZ hosting. There may be cases when you want to host an online game or Internet
application. This would require you to set up the Router to deliver incoming packets or data to a specific
computer. This also applies to the Internet applications you are using. The best way to get the 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 Router's Web-based Utility by going to http://192.168.1.1 or the IP address of the Router. Go
to the Advanced Setup => Forwarding tab.
B. Select the Service from the pull-down menu. If the Service you need is not listed in the menu, click the
Service Management button to add the new Service Name, and enter the Protocol and Port Range. For
example, if you have a web server, you would enter the range 80 to 80. Click the Add to List button. Then
click the Save Setting button. Click the Exit button.
C. Enter the IP Address of the server that you want the Internet users to access. 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 C: Finding the MAC Address and IP Address for Your Ethernet Adapter" for details on getting an
IP address. Then check the Enable checkbox for the entry. Consider the examples below:
Application Start and End
UT 7777 to 27900
Halflife 27015 to 27015
PC Anywhere 5631 to 5631
VPN IPSEC 500 to 500
D. Click the Add to List button, and configure as many entries as you like.
When you have completed the configuration, click the Save Settings button.
