EtherFast Cable/DSL Router with 8-Port Switch
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 example below:
When you have completed the configuration, click the
Save Settings
button.
8. 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.
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 C: 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
Save Settings
button.
