Special Applications
Some applications, such as Internet gaming, videoconferencing, Internet
telephony and others, require multiple connections. These applications
cannot work with Network Address Translation (NAT) enabled. If you
need to run applications that require multiple connections, use the
following screen to specify the additional public ports to be opened for
each application.
Specify the public port number normally associated with an application in
the Trigger Port field. Set the protocol type to TCP or UDP, then enter the
ports that the application requires. The ports may be in the format 7, 11,
57, or in a range, e.g., 72-96, or a combination of both, e.g., 7, 11, 57, 72-
96.
Popular applications requiring multiple ports are listed in the Popular
Applications field. From the drop-down list, choose the application and
then choose a row number to copy this data into.
Note: Choosing a row that already contains data will overwrite the
current settings.
