Advanced Port Forwarding Page
This page allows you to run a publicly accessible server on the LAN by specifying the
mapping of TCP/UDP ports to a local PC. This enables incoming requests on specific
port numbers to reach web servers, FTP servers, mail servers, etc. so that they can
be accessible from the public Internet.
A table of commonly used Port numbers is also displayed on the page for your
convenience.
To map a port, you must enter the range of port numbers that should be forwarded
locally and the IP address to which traffic to those ports should be sent. If only a
single port specification is desired, enter the same port number in the "start" and
"end" locations for that IP address.
The ports used by some common applications are:
• FTP: 20, 21
• HTTP: 80
• NTP: 123
• Secure Shell: 22
• SMTP e-mail: 25
• Telnet: 23
