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.
