Applications and Gaming > DMZ
The DMZ (Demilitarized Zone) feature allows one
network computer to be exposed to the Internet for use
of a special-purpose service such as Internet gaming or
videoconferencing . DMZ hosting forwards all the ports
at the same time to one computer . The Port Range
Forwarding feature is more secure because it only opens
the ports you want to have opened, while DMZ hosting
opens all the ports of one computer, exposing the
computer to the Internet .
