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.
