Alternatively known as a DMZ host, DMZ is short for demilitarized zone and is a buffer area between outside users (the Internet) and a private (local) server. DMZs are often used by corporations and contain a device that accepts Internet traffic such as DNS, FTP and Web servers.

By default, DMZ is disabled on most routers to add an extra layer of security. However, port forwarding is enabled on a network router, the DMZ may need to be turned on as well.
