7.5 NAT Port Forwarding Screen
Port forwarding allows users to define the local servers to which incoming services will
be forwarded by creating a firewall between the internal network and the Internet. A
tunnel is created so that computers on the Internet can communicate to computers on
a user’s LAN through a single port. This is useful for running Web servers, game
servers, FTP servers, and video conferencing and is more secure than DMZ. A
common example is one computer running a Web server on port 80 and another
computer running an FTP server on port 23, each with the same IP address.
