Advanced Port Triggers Page
This page allows you to configure dynamic triggers to specific devices on the LAN.
This allows for special applications that require specific port numbers with
bi-directional traffic to function properly. Applications such as video conferencing,
voice, gaming, and some messaging program features may require these special
settings.
The Advanced Port Triggers are similar to Port Forwarding except that they are not
static ports held open all the time. When the Configuration Manager detects
outgoing data on a specific IP port number set in the "Trigger Range," the resulting
ports set in the "Target Range" are opened for incoming (sometimes referred to as
bi-directional ports) data. If no outgoing traffic is detected on the "Trigger Range"
ports for 10 minutes, the "Target Range" ports will close. This is a safer method for
opening specific ports for special applications (e.g. video conferencing programs,
interactive gaming, file transfer in chat programs, etc.) because they are dynamically
triggered and not held open constantly or erroneously left open via the router
administrator and exposed for potential hackers to discover.
