Port Forwarding (Inbound Rules)

Because the modem router uses Network Address Translation (NAT), your network presents only one IP address to the Internet, and outside users cannot directly address any of your local computers. However, by defining an inbound rule you can make a local server (for example, a Web server or game server) visible and available to the Internet.

The inbound rule that you create tells the modem router to direct inbound traffic for a particular service to one local server based on the destination port number. This is also known as port forwarding.
