4.6.7 Port
Forwarding
Using the Port Forwarding page, you can provide local services (for example web hosting) for
people on the Internet or play Internet games. When users send this type of request to your
network via the Internet, the ADSL Router will forward those requests to the appropriate PC. Port
forwarding can be used with DHCP assigned addresses but remember that a DHCP address is
dynamic (not static). For example, if you were configuring a Netmeeting server, you would want
to assign this server a static IP address so that the IP address is not reassigned. Also remember
that if an Internet user is trying to access an Internet application, they must use the WAN IP
address. The port forwarding will translate the WAN IP address into a LAN IP address.
To configure a service, game, or other application select the external connection (for example the
Internet connection), from the HOME screen, click ADVANCED and select Port Forwarding. Next
select the computer hosting the service and add the corresponding firewall rule. If you want to
add a custom application, select the User category, click New and fill in the port, protocols and
description for your application.
For example, if you want to host a Netmeeting session, from the HOME screen, click ADVANCED
and select Port Forwarding. First select the IP address for your Netmeeting server. Next select
the Audio/Video category and add Netmeeting to the applied rules box. To view the management
rules, highlight Netmeeting and select view; this will display the pre configured protocols and
ports that Netmeeting will use. Now assuming that your WAN connection is correct, you can run
Netmeeting from your server and call users that are on the Internet. If you know your WAN IP
address, users can call you.

4.6.7.1 DMZ configuration
Setting a computer (on your local network) as a DMZ forwards any network traffic that is not
redirected to another computer via the port-forwarding feature to the computer's IP address. This
opens the access to the DMZ computer from the Internet.
