5.4.3 Special Applications

Some applications require multiple connections, such as Internet gaming
and video conferencing. These applications cannot work when Network
Address Translation (NAT) is enabled. If you need to run applications that
require multiple connections, specify the port normally associated with an
application in the "Trigger Port" field. Select the protocol type as TCP or
UDP and then enter the public ports associated with the trigger port to
open them for inbound traffic.
