- The DMZ Feature in a Linksys Gateway
The DMZ (Demilitarized Zone) is basically a computer or sub network that adds an additional layer of security to an organization's LAN by sitting between it and an external network, such as the public Internet.
The DMZ feature in a Gateway allows one network computer to be exposed to the Internet for use of a special-purpose service such as Internet gaming or videoconferencing. DMZ hosting forwards all the ports at the same time to one computer.
You would want to use DMZ over Port Range Forwarding when you only want to expose one particular computer to the Internet. This is because Port Range Forwarding only opens the ports that you want to have opened, while DMZ hosting opens all the ports of one computer, therefore exposing only that computer to the Internet.
The following diagram illustrates an example of DMZ.
To enable DMZ hosting, follow the guide below.
Access the Web-Based Utility of the Gateway. For instructions, click here.
Click on Applications & Gaming.
Click on DMZ.
Next to DMZ Hosting, click on Enable.
Enter the DMZ Host IP Address of the computer you want to expose.
Click on Save Settings to confirm your changes.
