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
42.
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.
Tip:
To ensure that your server computer always has twireless routerhe same
IP address, use the reserved IP address feature of your wireless router.
See
Using Address Reservation
on page

use reserved IP addresses.
To configure port forwarding to a local server:
1.
