Netgear routers designed for homes and small office networks perform a function called Network Address Translation, or NAT, to share a single Internet connection, such as cable or DSL, with multiple computers on the local network. However, for a computer or other device connected to the router to transmit data upstream, Port Address Translation, or PAT, must be performed for individual ports per application. You can configure individual computers and applications to access upstream services through the port forwarding feature of the Netgear router.
1. Open a Web browser and type "192.168.1.1" without quotes into the address bar. Press "Enter."
2. Type "admin" without quotes for the username and password. Press "Enter."
3. Click "Port Forwarding / Port Triggering."
4. Click "Add Custom Service."
5. Enter the name for the application. For example, type "FTP Server." The name can be of your choosing.

7. Enter the IP address of the desired computer, and then click "Apply."
