4. 7. 2. Port Triggering
Port triggering can specify a triggering port and its corresponding external ports. When
a host in the local network initiates a connection to the triggering port, all the external
ports will be opened for subsequent connections. The router can record the IP address
of the host. When the data from the Internet return to the external ports, the router can
forward them to the corresponding host. Port triggering is mainly applied to online
games, VolPs, video players and common applications including MSN Gaming Zone,
Dialpad, QuickTime 4 players and more.
