8.6.5 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 lead to 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.
Note:
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.
