Selecting Port Forwarding from the left menu bar brings up the Port Forwarding configuration
page. Port Forwarding is a technique for transmitting and receiving network traffic through a router
that involves re-writing the source and/or destination IP addresses and usually the TCP/UDP port
numbers of IP packets as they pass through. The various routing configurations will be displayed in
the IP mapping table at the bottom of the screen. Refer to Figure 8.1 below.
