to apply the settings.
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 Protocol drop-down list. Under External Port, enter
the port 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 Local IP Address field, enter the IP address of the PC that provides the
service.
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.

Port Triggering
If you configure port triggering for a certain application, you must 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.
