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.
