Port Trigger Panel
Some applications require multiple ports open for communication, many of which may be initiated
by a computer on the WAN. Examples of this include video conferencing, VoIP (Internet
telephony), and Internet gaming.
With port triggering, the device monitors outgoing data on specific port numbers (trigger ports).
The device keeps track of the IP address of the computer that sends data on these trigger ports,
so that when incoming data on the forward ports arrives, the device sends the incoming data to
the same computer.
Before you can use or configure port triggering, you must enable it, as explained in "Enabling Port
Triggering" below.
