If the application you require is not in the list, manually enter
the information.
Select the protocol for the service you are providing from the

number of the service you are providing. In the
Internal Port
field, enter the internal port number, to which service requests
are to be forwarded. In the

Example
The Web server is configured to react to requests on port 8080.
However, the requests from websites enter the Web server via
port 80 (standard value). If you add the PC to the forwarding
table and define port 80 as the public port and port 8080 as an
internal port, all requests from the Internet are diverted to the
service with port 80 on the Web server of the PC you have
defined with port 8080.

4.4.3.3 Port Triggering
If you configure port triggering for a certain application, you
need to determine a so-called trigger port and the protocol
(TCP or UDP) that this port uses. You then assign the public
ports that are to be opened for the application to this trigger
port. You can select known Internet services or manually
assign ports or port blocks.
