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

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.
