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.
