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 Advanced 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.
