4-4 DMZ Host

The DMZ Host application allows unrestricted 2-way communication between a single LAN

PC and other Internet users or servers. This application is useful for supporting special-purpose

services such as video-conferencing and gaming, that require proprietary client software and/or

2-way user communication.

To use this application, you must first obtain a fixed Public IP Address from your ISP. Note that

in order to provide unrestricted access, the Firewall provided by the Wireless Broadband router

to protect this port is disabled, thus creating a potentially serious security risk.

It is recommended that this application is disabled when it is not in use by entering “0” in the

“DMZ Host”field.

The Multi DMZ allows you to map the public IP addresses to your LAN PCs, should you get

more than one public IP address from your ISP. This function is useful to set up your servers,

such as an FTP server, web server, and so on, with public IP addresses, but still keep them

within your LAN group.

With the public IP addresses, Internet users will access your servers more easily and those

servers can still communicate with other PCs in you LAN by using Network Neighborhood.

Before setting up a LAN PC to act as a DMZ Host, you should configure it
