3.4.5 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 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.
Parameters Description
Enable Enable/disable DMZ
Public IP Address The IP address of the WAN port or any other Public IP
addresses given to you by your ISP
IP Address of Virtual DMZ Input the IP address of a particular host in your LAN that will
receive all the packets originally going to the WAN port/Public IP
address above.
Action Press <Add> to add DMZ rule.
