Some applications require that specific ports in the Router's
firewall shall be opened for access by the remote parties.
Port Trigger dynamically opens up the “Open Ports” in the firewall
when an application on the LAN initiates a TCP/UDP connection to a
remote party using the “Triggering Ports”.
The Router allows the remote party from the WAN side to
establish new connections back to the application on the LAN side
using the “Open Ports”.
A maximum of 32 entries can be configured.
