Address Translation

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.

Demilitarized Zone Client

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.
