the external port needs to be converted to a different port number
used by the server on the LAN side. Up to 32 entries can be

Port Triggering Configuration
Some applications require that specific ports in the Router's
firewall be opened for access by the remote parties.
Port Trigger dynamically opens 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”.
Up to 32 entries can be configured.
