protection from hacker attacks and has the flexibility to allow you to map
Private IP Addresses to Public IP Addresses for key services such as Websites

6.8.1 DMZ Host Setup
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. The DMZ
function allows you to re-direct all packets going to your WAN port IP address to
a particular IP address in your LAN. The difference between the virtual server
and the DMZ function is that the virtual server re-directs a particular
service/Internet application (e.g. FTP, websites) to a particular LAN
client/server, whereas DMZ re-directs all packets (regardless of services) going
to your WAN IP address to a particular LAN client/server.
