Add a Custom Service
To define a service, game, or application that does not appear in the Service Name list, you
have to first determine which port number or range of numbers used by the application. You
can usually determine this information by contacting the publisher of the application or user
groups or newsgroups.
To add a custom service:
1. Select Advanced > Advanced Setup > Port Forwarding/Port Triggering.
2. Select Port Forwarding as the service type.
3. Click the Add Custom Service button to display the following screen:
4. In the Service Name field, enter a descriptive name.
5. In the Service Type list, select the protocol. If you are unsure, select TCP/UDP.
6. Specify the port settings:
•External Starting Port and External Ending Port. These are the starting number
and ending number for the public ports at the Internet interface. For single port
forwarding, the number in the External Starting Port and External Ending Port fields
can be the same.
•Use the same port range for Internal port. This check box is selected by default. If
you want to use different ports, clear this check box and specify the internal ports.
