4.3.4 Forwarding Traffic from the WAN to a Local Computer

A server NAT address mapping rule allows computers behind the NAT be
accessible to the outside world. To have the ZyXEL Device forward incoming traffic
to a specific computer on your local network, you should also create a port
forwarding (server mapping) rule.
In this example, you want to forward FTP traffic using port 21 to the computer
with the IP address of 192.168.1.39.
