Port forwarding, or tunneling, is the behind-the-scenes process of intercepting data traffic headed for a computer's IP/port combination and redirecting it to a different IP and/or port. A program that's running on the destination computer (host) usually causes the redirection, but sometimes it can also be an intermediate hardware component
Nov 28, 2016 · Port triggering is a dynamic extension of port forwarding that is useful in these cases: An application must use port forwarding to more than one local computer (but not simultaneously).

Port forwarding using the outside IP address. We will start with the most common scenario. When someone connects to TCP port 80 on the outside interface of R2 then it should be forwarded to R1. Here’s how to do it: R2(config)#ip nat inside source static tcp 192.168.12.1 80 192.168.23.2 80 extendable. The NAT rule above is pretty straight forward.
