Configuring Port Range Triggering

The Firewall > Port Range Triggering window displays the configurations of triggered range and forwarded range of ports that are used by applications that request ports to be opened on demand. Port Range Triggering is an NAPT (Network Address Port Translation) feature.

Port Range Triggering is used for special applications that can request a port to be opened on demand. For this feature, the router watches outgoing packets for specific port numbers. This triggers the router to allow the incoming packets within the specified forwarding range and forward those packets to the triggering personal computer. One of the example applications is QuickTime. It would use port 1000 for outgoing packets and 2000 for incoming packets.

To configure port range triggering for the router, follow these steps:

STEP 1 Click Firewall > Port Range Triggering.

STEP 2 Configure port range triggering settings for the router:
