If you have been experimenting with the advanced features of your wireless network, you may wonder what is DMZ on a router. The best routers tend to include this feature, but what is it and why would look to access it? Keep reading to find out.


  • DMZ stands for Demilitarized Zone and refers to an internal network security feature accessible via most modern routers.
  • To enable the DMZ layer of security, head to your router’s settings page by inputting its IP address into the address field of a web browser.
  • Look for “Security Settings” or “Advanced Settings” and enable the feature. Save your changes and restart the router to ban untrusted networks and network interfaces.

What is Router DMZ?

As you would expect, DMZ stands for “demilitarized zone” though this is very different from the typical application of this term. A demilitarized zone (DMZ) when referring to a wireless network is a security feature that protects an internal local area network (LAN) from untrusted traffic. A DMZ ensures a private network or LAN remains secure, keeping unwanted traffic and nefarious mobile devices away. This is why it’s good to know the security type of your WiFi, so you can keep it protected. If your network remains secure, you won’t ever have to learn how to unbrick a router, as it likely won’t brick in the first place.

Insider Tip

DMZ is not the only advanced security feature available to modern routers. Check out the settings page for more.

How to Enable DMZ on a Router

The process here varies according to your specific router, so if you are comparing a Linksys Velop tri-band vs a dual-band, you may have to take slightly different steps. Still, we have kept these guidelines fairly universal.


Ensure your network is operating correctly, looking for an Ethernet cable connecting your router to your modem. Check the status of your network by using a mobile device to connect to the Internet.


Next, you’ll have to access the router’s admin control page or settings panel. The process here varies, so check the instructions that accompanied your router or conduct a simple web search.


In most cases, you can access the settings page by inputting the router’s public IP address into the address field of a web browser via computer or mobile device. If you want to find this static IP address, check the sticker located on the exterior of your router.


Once you have successfully signed in to your router’s settings page, look for security settings, which could be located under “Advanced Settings.” Enable DMZ and save your changes. In some cases, you may have to restart your router and modem. Once you have done this, DMZ should be enabled and you can look forward to increased network security.

How does a DMZ network work?

A DMZ is like a buffer between your Internet connection and any perimeter networks floating within range of your internal network. These internal servers filter out any unwanted traffic for the external user.

Is a DMZ safe?

When it comes to protecting your IP address and private network from security risks, a DMZ is extremely safe and better than a single firewall. If you are looking for additional security, give it a shot.

Where to find your model number?

If you need your router’s model number to create a private network, change the IP address, or change any internal network settings, look on the back of the router itself.

STAT: DMZ networks have been central to securing global enterprise networks since the introduction of firewalls. They protect organizations’ sensitive data, systems, and resources by keeping internal networks separate from systems that could be targeted by attackers. (source)
