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.
Click the
List of well known special applications
link for more
information.
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 of a
single port, or in a range, e.g., 72-96, or a combination of both.
