" To allow traffic from the WAN to be forwarded through the ZyXEL Device, you

must also create a firewall rule. Refer to Section 2.5.5 on page 67 for more

information.

2.5.4 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.
