4.2.7.4 Demilitarized Zone (DMZ)
If users have a local client PC that cannot run an Internet application (e.g. Games)
properly from behind the NAT firewall, the router can open the client to an unrestricted
two-way Internet access by defining a DMZ Host. The DMZ function allows re-direct of
all packets going to the WAN port IP address to a particular IP address in the 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.
Parameter
Description
Enable DMZ
Allow the DMZ to be enabled. If there is a conflict between
the Virtual Server and the DMZ setting, then Virtual Server
function will have priority over the DMZ function.
Public IP Address
The IP address of the WAN port or any other Public IP
addresses given by the user’s ISP.
Client PC IP Address
Input the IP address of a particular host in the LAN that will
receive all the packets originally going to the WAN port/Public
IP address above. Users need to give the LAN PC clients a
fixed/static IP address for DMZ to work properly.
