DMZ

If you have a client PC that cannot run an Internet application (for example, games)

properly from behind the NAT firewall, then you can open up the firewall restrictions

to allow 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 (for example 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.
