9.4.5 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.
