8.2 DMZ Host
This section describes the NAT > DMZ page.
8.2.1 Introduction to DMZ host
The DMZ (Demilitarized Zone) host allows one local host to be exposed to the Internet for
the use of a special service such as online game or video conferencing. When receiving
the requests initiated from outside users, the Device will directly forward these requests to
the specified DMZ host.
For the Device that has multiple WAN interfaces, it allows you to create one global DMZ
host, and several interface DMZ hosts which are bound to each WAN interface
respectively.
Ɣ Global DMZ host: You can access the global DMZ host through different Internet
connections at the same time.
Ɣ Interface DMZ host: You can only access the interface DMZ host through the
corresponding Internet connection.
Note
When a local host is designated as the DMZ host, it loses firewall protection provided
by the Device. As the DMZ host is exposed to many exploits from the Internet, it may
be used to attack your network.
