Configuring Port Triggering
Port triggering allows devices on the LAN or DMZ to request one or more ports to
be forwarded to them. Port triggering waits for an outbound request from the LAN/
DMZ on one of the defined outgoing ports, and then opens an incoming port for
that specified type of traffic. Port triggering is a form of dynamic port forwarding
while an application is transmitting data over the opened outgoing or incoming
ports.
