5. I am not able to access the Setup page of the Router’s web-based utility.
• Refer to “Problem #3, I want to test my Internet connection” to verify that your computer is properly
connected to the Router.
• Refer to “Appendix E: Finding the MAC Address and IP address for Your Ethernet Adapter” to verify that
your computer has an IP Address, Subnet Mask, Gateway, and DNS.
• Set a static IP address on your system; refer to “Problem #2: I need to set a static IP address.”
• Refer to “Problem #10: I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up
window.”
6. I need to set up a server behind my Router and make it available to the public.
To use a server like a web, ftp, or mail server, you need to know the respective port numbers they are using.
For example, port 80 (HTTP) is used for web; port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and
port 110 (POP3 incoming) are used for the mail server. You can get more information by viewing the
documentation provided with the server you installed.
Follow these steps to set up port forwarding through the Router’s web-based utility. We will be setting up
web, ftp, and mail servers.
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 Range Forward tab.
2. Enter any name you want to use for the Application.
3. Enter the Start and End Port range of the service you are using. For example, if you have a web server,
you would enter the range 80 to 80.
4. Select the protocol(s) you will be using, TCP and/or UDP.
5. 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 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:
When you have completed the configuration, click the Save Settings button.
Application Start and End Protocol IP Address Enabled
Web server 80 to 80 Both 192.168.1.100 X
FTP server 21 to 21 TCP 192.168.1.101 X
SMTP (outgoing) 25 to 25 Both 192.168.1.102 X
POP3 (incoming) 110 to 110 Both 192.168.1.102 X

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:
1. Access the Router’s web interface by going to http://192.168.1.1 or the IP address of the Router. Go to
the Applications & Gaming => Port Range Forward tab.
2. Enter any name you want to use for the Application.
3. Enter the Start and End Port range of the service you are using. For example, if you want to host
Unreal Tournament (UT), you would enter the range 7777 to 27900.
4. Select the protocol(s) you will be using, TCP and/or UDP.
5. 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 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:
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.)
