Advanced Port Triggers Page
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 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
or bi-directional data. If no outgoing traffic is detected on the “Trigger Range” ports for
10 minutes, the “Target Range” ports 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.
