The demilitarized zone (DMZ) is a technology that enables the ONT to forward all received
packets through a specified internal server. The technology enables a computer in the LAN to
be completely exposed to all users on the Internet or enables the mutual communication without
restrictions between a host with a specified IP address and other users or other servers on the
Internet. In this way, many applications can run on the host with the specified IP address. The
host with the specified IP address receives all connections and files that can be identified.
CAUTION
If the LAN-side device does not provide website service or other network services, do not set
the device to a DMZ host because all ports of a DMZ host are opened to the Internet.
