Chapter 8 Configure the Router in Hotspot Router Mode
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 192.168.0.100.
2. Visit http://tplinkwifi.net , and log in with the username and password you set for the
router.
3. Go to Forwarding > DMZ .
4. Select Enable and enter the IP address 192.168.0.100 in the DMZ Host IP Address
filed.
5. Click Save .
Done!
You’ve set your PC to a DMZ host and now you can make a team to game with other
players.
8. 7. 4. UPnP
The UPnP (Universal Plug and Play) protocol allows the applications or host devices
to automatically find the front-end NAT device and send request to it to open the
corresponding ports. With UPnP enabled, the applications or host devices on the
local network and the Internet can freely communicate with each other realizing the
seamless connection of the network. You may need to enable the UPnP if you want
to use applications for multiplayer gaming, peer-to-peer connections, real-time
communication (such as VoIP or telephone conference) or remote assistance, etc.
Tips:
• UPnP is enabled by default in this router.
• Only the application supporting UPnP protocol can use this feature.
