External Port This is the port number used by the server
or Internet application. Internet users must connect using
this port number. Check with the software documentation
of the Internet application for more information.
Internal Port This is the port number used by the Router
when forwarding Internet traffic to the PC or server on
your LAN. Normally, this is the same as the External Port
number. If it is different, the Router performs a “Port
Translation”, so that the port number used by Internet
users is different from the port number used by the server
or Internet application.

For example, you could configure your Web Server to
accept connections on both port 80 (standard) and port
8080. Then enable Port Forwarding, and set the External
Port to 80, and the Internal Port to 8080. Now, any traffic
from the Internet to your Web server will be using port
8080, even though the Internet users used the standard
port, 80. (Users on the local LAN can and should connect
to your Web Server using the standard port 80.)
