6.2 Port Triggering
Some services use a dedicated range of ports on the client side and a dedicated range of ports on
the server side. With regular port forwarding you set a forwarding port in NAT to forward a service
(coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The
problem is that port forwarding only forwards a service to a single LAN IP address. In order to use
the same service on a different LAN computer, you have to manually replace the LAN computer's IP
address in the forwarding port with another LAN computer's IP address.
