In some situations, it is ben-

eﬁ cial to have a client network

device designated as a catch-

all, with all ports opened to

enable better functionality

with services like messaging

or gaming.
Using a Demilitarized zone

will allow one local network

device to be exposed to the

Internet for use of a special-

purpose service such as

Internet gaming or video-

conferencing. DMZ hosting

forwards all the ports at the same time to the selected device.
Packet Filtering is more secure as it only opens the ports designated to be opened, while a Demili-

atrarized Zone will open every port of a designated device.
