Free Applications from Port Restriction by DMZ

When a PC is set to be a DMZ (Demilitarized Zone) host in the local network, it is totally

exposed to the internet. This 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, like 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 hazard. If

DMZ is not in use, please disable it in time.

Allow the home PC to 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

with all ports opened.

1.

Assign a static IP address to your PC, for example

192.168.1.100.

2.

Visit

http://tplinkmodem.net

, and log in with the password

you set for the router.

3.

Go to

Advanced

>

NAT Forwarding

>

DMZ

.

4.

Enable DMZ.

5.

Enter the IP address 192.168.1.100 in the

DMZ Host IP

Address

field.

6.

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.
