2.7.4 DMZ 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.

DMZ Host Input the IP address of a particular host in your LAN that will receive

Note: You need to give your LAN PC clients a fixed/static IP address for DMZ to
