4.2.4 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 ZyWALL 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.
