Special Application
Some software applications require special or multiple
connections to the Internet and these would normally
be blocked by the rewall. For example Internet
Telephony or Video conferences require multiple
connections. So that these special applications can
work properly and are not blocked, the rewall needs
to be told about them. In each instance there will be
a trigger port and incoming port(s), where traf c on
the trigger port tells the rewall to open the incoming
ports.
Special Application allows the router to keep track of
outgoing data for speci c port numbers. The router
remembers which computer sends out what data, so
when the requested data returns through the router,
the data is sent back to the proper computer by way
of IP address and port mapping rules.
