Port Forwarding

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 N300 wireless modem 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 Configuring the WAN Setup Options on page 117.”

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.

Select Security > Port Forwarding in the main menu. The Port Forwarding screen displays:

want:

• Always. Always log traffic considered by this rule, whether it matches or not. This is

useful when debugging your rules.

• Match. Log traffic only if matches this rule. (The action is determined by this rule.)

not determined by this rule.)
