What is DMZ?

Demilitarized Zone: 

 

In computer networks, a DMZ (demilitarized zone) is a computer host or small 

network inserted as a neutral zone between a company´s private network and the 

outside public network. It prevents outside users from getting direct access to a 

server that has company data. (The term comes from the geographic buffer zone 

that was set up between North Korea and South Korea following the UN police action 

in the early 1950s.) A DMZ is an optional and more secure approach to a firewall and 

effectively acts as a proxy server as well.  

 

In a typical DMZ configuration for a small company, a separate computer (or host in 

network terms) receives requests from users within the private network for access 

to Web sites or other companies accessible on the public network. The DMZ host 

then initiates sessions for these requests on the public network. However, the DMZ 

host is not able to initiate a session back into the private network. It can only forward 

packets that have already been requested.  

 

Users of the public network outside the company can access only the DMZ host. The 

DMZ may typically also have the company´s Web pages so these could be served 

to the outside world. However, the DMZ provides access to no other company data. 

In the event that an outside user penetrated the DMZ hosts security, the Web pages 

might be corrupted but no other company information would be exposed. D-Link, a 

leading maker of routers, is one company that sells products designed for setting up 
a DMZ

How do I configure the DMZ Host?

The DMZ feature allows you to forward all incoming ports to one computer on the 

local network. The DMZ, or Demilitarized Zone, will allow the specified computer 

to be exposed to the Internet. DMZ is useful when a certain application or game 

does not work through the firewall. The computer that is configured for DMZ will be 

completely vulnerable on the Internet, so it is suggested that you try opening ports 

from the Virtual Server or Firewall settings before using DMZ. 

 

 

Step 1

 

Find the IP address of the computer you want to use as the DMZ host. 

 

 

To find out how to locate the IP Address of the computer in Windows XP/2000/ME/9x 

or Macintosh operating systems please refer to Step 4 of the first question in this 

section (Frequently Asked Questions).
