How Port Forwarding Differs from Port Triggering
The following points summarize the differences between port forwarding and port triggering:
•
Port triggering can be used by any computer on your network, although only one
computer can use it at a time.
•
Port forwarding is configured for a single computer on your network.
•
Port triggering does require that you know the computer’s IP address in advance. The IP
