Port Forwarding
Using the Port Forwarding page you can provide local services (such as web hosting) for people on the Internet. When
users send this type of request to your network via the Internet, the 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. If you were configuring a Netmeeting server, for example, 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 feature will translate the WAN IP address into a
LAN IP address.
