DMZ
The DMZ Host is a local computer exposed to the Internet. When setting a
particular internal IP Address as the DMZ Host, all incoming packets will be
checked by the firewall and NAT algorithms then passed to the DMZ Host.
For example, if you have a local client PC that cannot run an Internet application
(e.g. Games) properly from behind the NAT firewall, then you can open the client
up to unrestricted two-way Internet access by defining a DMZ Host.
