2.6.4 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.
Note: DMZ function works only when the NAT function is enabled.
