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.
