Port Triggering.
Some applications require that the remote parties
open the specific ports in the router’s firewall for access. For
instance, an application uses port 25 for requests and port 113 for
replies. If a computer on the LAN connects to port 25 on a
remote server hosting this application, using Port Triggering on
the router, incoming connections to port 113 (from the remote
server) could be redirected to the PC that initiated the request. A
maximum of 32 entries can be configured.
