How to make applications free from port restriction by DMZ

When a PC is set to be a DMZ (Demilitarized Zone) host on the local network, it is totally exposed to the internet, which can realize unlimited bidirectional communication between internal hosts and external hosts. The DMZ host becomes a virtual server with all ports opened. When you are not clear about which ports to open in some special applications, such as IP camera and database software, you can set the PC to be a DMZ host.

Note:

When DMZ is enabled, the DMZ host is totally exposed to the internet, which may bring some potential safety hazards. If DMZ is not in use, please disable it in time.

I want to:

Make the home PC join the internet online game without port restriction.

For example, due to some port restrictions, when playing online games, you can log in normally but cannot join a team with other players. To solve this problem, set your PC as a DMZ host with all ports open.

How can I do that?

1. Assign a static IP address to your PC, for example, 192.168.1.100.

2. Log in to the web-based interface of the router. If you don’t know how to do that, please refer to How to log into the web-based interface of the MERCUSYS Wireless AC/AX Router.

3. Go to Advanced > NAT Forwarding > DMZ and select Enable DMZ.

4. Enter the IP address 192.168.1.100 in the DMZ Host IP Address filed.

5. Click Save.

Done! The configuration is completed. You've set your PC to a DMZ host, and now you can make a team to play with other players.
