8.8.5. DMZ Server
DMZ (Demilitarized Zone), a special network zone that is different from the external network or the
internal network. Servers that are allowed to access the external network, such as Web and e-mail,
connect to the DMZ. The internal network is protected behind the Trust Zone interface, and is not
allowed any user to access. Therefore, the internal and external networks are separated, which can
meet user’s secrecy demand.
Usually, there are some public servers in DMZ, such as Web, Mail, and FTP. Users from the external
network can access services in DMZ, but they cannot obtain the company’s secret information or
personal information that is stored on the internal network. Even though servers in the DMZ are
damaged, it does not cause secret information loss on the internal network.
Choose Network Application > DMZ Server and the DMZ Server page is displayed.

Default DMZ Server: Enter the IP address of a PC that serves as the DMZ server.
When PC on the internal network is set to be the DMZ host, all interfaces of the PC will be
exposed to the Internet and the PC will risk great security.
Unless necessary, please do not set the DMZ casually. After the DMZ host is set,
mappings of all the interfaces will point to the DMZ host and the port mappings that point
to other hosts will be invalid.
