2.6.5 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 differenc e 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.
Parameters Description
Enable DMZ Select Yes to enable DMZ
Select No to disable DMZ
Note: If there is a conflict between the Virtual Server and the
DMZ setting, then Virtual Server function will have priority over
the DMZ function.
