Why does my game crash on DMZ? Super frustrating!

If you are experiencing game crashes while playing on DMZ, it can be a frustrating experience. DMZ or Demilitarized Zone is a feature in routers that allows a device to bypass the firewall and have unrestricted access to the internet. This feature is often used by gamers to improve their online gaming experience. However, it can also cause issues such as game crashes.

Here are some possible reasons why your game is crashing on DMZ:

1. Network congestion: DMZ can cause network congestion, which can lead to game crashes. This happens when too many devices are connected to the network, and the router is unable to handle the traffic.

2. Firewall issues: DMZ bypasses the firewall, which can leave your device vulnerable to attacks. If your firewall is not properly configured, it can cause game crashes.

3. Port forwarding issues: DMZ can interfere with port forwarding, which is necessary for some games to function properly. If your ports are not properly forwarded, it can cause game crashes.

Here are some steps you can take to fix the issue:

1. Disable DMZ: If you are experiencing game crashes on DMZ, try disabling it and see if the issue persists. This will help you determine if DMZ is the cause of the problem.

2. Configure your firewall: Make sure your firewall is properly configured to allow your game to function properly. You can do this by opening the necessary ports and allowing the game to bypass the firewall.

3. Check your network: Make sure your network is not congested and that there are no other devices using too much bandwidth. You can do this by disconnecting other devices and running a network speed test.

4. Contact your ISP: If the issue persists, contact your internet service provider (ISP) and ask them to troubleshoot the issue. They may be able to identify the problem and provide a solution.

In conclusion, game crashes on DMZ can be caused by a variety of issues, including network congestion, firewall issues, and port forwarding issues. By following the steps outlined above, you can identify the cause of the problem and take steps to fix it. If the issue persists, don’t hesitate to contact your ISP for assistance.


In conclusion, we hope that the steps provided above have helped you resolve the issue of game crashes on DMZ. Remember to always prioritize your network security and ensure that your firewall is properly configured. If you continue to experience issues, don’t hesitate to seek assistance from your ISP or a professional technician. Happy gaming!
