Firewall - Port Range Forwarding

This is one of the NAPT (Network Address Port Translation) features. The Port Range For-
warding screen allows you to set up public services on your network, such as web servers, ftp
servers, e-mail servers, or other specialized Internet applications that use one or multiple port
numbers (e.g. video conference). The port numbers being used will not change while forward-
ing to the local network. This allows users on the Internet to access this server by using the
WAN port IP address and the pre-defined port numbers. When users send these types of
requests to your WAN port IP address via the Internet, the NAT Router will forward those
requests to the appropriate servers on your LAN.
