Port Forwarding
When network address translation (NAT) is enabled on the CPE, only the IP address on the WAN side
is open to the Internet. If a computer on the LAN is enabled to provide services for the Internet (for
example, work as an FTP server), port forwarding is required so that all accesses to the external
server port from the Internet are redirected to the server on the LAN.

Choose Firewall > Port Forwarding .
