Port Forwarding
Port forwarding is a way of creating a tunnel through the AP+4’s
firewall so that computers on the Internet can communicate via a
single port to one of the computers on your LAN. Port forwarding
is safer than creating a DMZ – where all ports on one computer
inside the LAN are opened to all Internet traffic – because only
one port (or a small series of ports) is exposed to the Internet.
