page if you need to allow public access to services
on computers that are connected to the LAN ports. Port Forwarding opens a
specified port or a port range for a service, such as FTP. Port Triggering opens a
port range for services such as Internet gaming that use alternate ports to
communicate between the server and LAN host. This page has the following
sections:
• Port Range Forwarding, page 44
• Port Triggering, page 47
To open this page: Click Setup > Forwarding in the navigation tree.

Port Range Forwarding
Port forwarding can be used to set up public services on your network. When
users from the Internet make certain requests to your network, the router can
forward those requests to computers that are equipped to handle the requests. If,
for example, you set the port number 80 (HTTP) to be forwarded to IP address
192.168.1.2, then all HTTP requests from outside users will be forwarded to
192.168.1.2.
You may use this function to establish a web server or FTP server via an IP
gateway. Make sure that you enter a valid IP address. (You may need to establish a
static IP address in order to properly run an Internet server.) For added security,
Internet users will be able to communicate with the server, but they will not
actually be connected. The packets will simply be forwarded through the router.
