Port Forwarding

Configuring Port Forwarding to Local Servers

Using the port forwarding feature, you can allow certain types of incoming traffic to reach servers

on your local network. For example, you might make a local Web server, FTP server, or game server visible and available to the Internet.

Use the Port Forwarding screen to configure the router to forward specific incoming protocols to computers on your local network. In addition to servers for specific applications, you can also specify a default DMZ server to which all other incoming protocols are forwarded. The DMZ server is configured in the WAN Setup screen, as discussed in ““Setting Up a Default DMZ Server” on page 5-4.

Before starting, you need to determine which type of service, application, or game you will provide, and the local IP address of the computer that will provide the service. Be sure the computer’s IP address never changes.

To configure port forwarding to a local server:

1.Log in to the gateway as described in “Logging In to Your Gateway” on page 1-4.

2.Select Port Forwarding under Advanced in the main menu. The Port Forwarding screen displays:
