2.5.4 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.

Parameters Description

Enable DMZ Enable/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.

WAN Port

The WAN port that the local client PC IP will bind to

Public IP Address

The IP address of the WAN port or any other Public IP

addresses given to you by your ISP. The WAN port may use

dynamic IP or static IP given by your ISP. If your ISP give you

more than one dynamic IP addresses, you have to assign the

session number that you want to apply.
