Port Triggering Setup
Some applications, such as online games, videoconferencing and VoIP telephony, re`uire multiple ports for inQound and outQound
trafc. If an application re`uires simultaneous use of incoming and an outgoing ports, congure port triggering to map a local port or
range of ports to a specic puQlic port. Sending packets out over the local port triggers the router to open an incoming local port that
is mapped to the same puQlic port and application as the outgoing local ports. The local application can communicate over the
incoming and outgoing ports fithout the need for creating a ged address.
