4.5.5 Allow WAN-to-LAN Traffic through the Firewall

By default, the ZyXEL Device blocks any traffic initiated from the WAN to the LAN. To have
the ZyXEL Device forward traffic initiated from WAN 1 to a local computer or server on the
LAN, you need to configure a firewall rule to allow it.
In this example, you create the firewall rules to allow traffic from the WAN to the following
servers on the LAN:
• Web server
• Mail server
• FTP server
