EtherFast Cable/DSL Router with 4-Port Switch
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 Applications & Gaming => Port Range Forwarding tab.
B. Enter any name you want to use for the Application.
C. Enter the port range of the service you are using. For example, if you have a web server, you would enter
the range 80 to 80.
D. Select the protocol you will be using, TCP or UDP, or select Both.
E. 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 C: Finding the MAC Address and IP Address for Your Ethernet Adapter" for details on
getting an IP address.
F. Check the Enabled option for the port services you want to use. 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
When you have completed the configuration, click the Save Settings button.
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 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:
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 Applications & Gaming => Port Range Forwarding 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. Click the DMZ tab.
