At the prompt, enter the number of the desired new position and click OK. Inbound Rules (Port Forwarding) 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 rule 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. Note: Some residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP might periodically check for servers and might suspend your account if it discovers any active services at your location. If you are unsure, refer to the acceptable use policy of your ISP.

Inbound Rules (Port Forwarding)
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 rule 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.
