Adding a Custom Rule
To define rule that does not appear in the Service list, you must first determine which port number

contacting the publisher of the application or user groups or newsgroups. When you have the port 
number information, follow these steps:
1.
In the Port Forwarding screen, enter the name of the rule in the Add Custom Rules section of 
the screen. 
2.
In the 
Starting Port 
field, enter the beginning port number.

Ending Port 
field.
