4. 6. 4. DMZ
When a PC is set to be a DMZ (Demilitarized Zone) host in 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:
DMZ is more applicable in the situation that users are not clear about which ports to open. When it 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 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 opened.
How can I do that?
1. Assign a static IP address to your PC, for example 192.168.1.100.
9. Visit http://mwlogin.net, and log in with your Mercusys ID or the password you set for
the router.
2. Go to Advanced > NAT Forwarding > DMZ and select Enable DMZ.
3. Click VIEW CONNECTED DEVICES and select your PC. The DMZ Host IP
Address will be automatically filled in. Or enter the PC’s IP address 192.168.1.100
manually in the DMZ Host IP Address field.
4. Click SAVE.
Done!
You’ve set your PC to a DMZ host and now you can make a team to game with other players.
