7.1.3. Port Triggering
Port triggering allows you to define a set of dynamic port-forwarding rules that will be activated as soon as a
device sends traffic to the Internet over a specific port(s), the trigger port(s).
The difference from the port forwarding function described in “7.1.2 Port forwarding” is:
Port triggering rules will only be activated if a local device is sending traffic over one of the trigger ports.
There must be outbound traffic first.
Port triggering rules forward traffic to any device that has initiated communication while port
forwarding only forwards to a specific fixed IP.
Port triggering rules allow you to translate the port numbers. Thus the incoming port can differ from the
target port.
