ADSL2+ Gateway with VoIP
C. Set a static IP address on your system; refer to "Problem #3: I need to set a static IP address on a PC."
D. 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 Gateway.
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 Gateway's web-based utility. We will be setting up web, ftp, and mail servers.
A. Access the Gateway's web-based utility by going to http://192.168.1.1 or the IP address of the Gateway.
Go to the Router > Application tab.
B. Select yes from the Enable drop-down menu.
C. Enter any name you want to use for the service.
D. Enter the port range of the service you are using. For example, if you have a web server, you would enter
the range 80 (in the Starting Port field) to 80 (in the Ending Port field).
E. Select the protocol you will be using, TCP or UDP, or select Both.
F. 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 B: Finding the MAC Address and IP Address for Your Ethernet Adapter" for details on
getting an IP address.
G. Follow the instructions in steps B-F for the port services you want to use. Consider the examples below:
Enable Service Name
yes Web server
yes FTP server
yes SMTP (outgoing)
yes POP3 (incoming)
When you have completed the configuration, click the Submit All Changes button.
