DMZ - Make Applications Free from Port Restriction
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 the 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.
For example, due to some port restriction, when playing the 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.
Here we take TP-Link Router as an example. Before you start, assign a static IP address to your PC, for example 192.168.0.100. Then follow the steps below:
- Visit http://tplinkwifi.net, and log in with your TP-Link ID or the password you set for the router.
- Go to Advanced > NAT Forwarding > DMZ and select Enable DMZ.
- Enter the IP address 192.168.0.100 in the DMZ Host IP Address filed.
- Click Save.
The configuration is completed! You’ve set your PC to a DMZ host and now you can make a team to game with other players.
