4. 7. 2. Port Triggering
Port triggering can specify a triggering port and its corresponding external ports. When
a host in the local network initiates a connection to the triggering port, all the external
ports will be opened for subsequent connections. The router can record the IP address
of the host. When the data from the internet return to the external ports, the router
can forward them to the corresponding host. Port triggering is mainly applied to online
games, VoIPs, video players and common applications including MSN Gaming Zone,
Dialpad, Quick Time 4 players and more.
Follow the steps below to configure the port triggering rules:
1. Visit
http://tplinkwifi.net , and log in with the username and password you set for the
router.
2. Go to Forwarding > Port Triggering .
3. Click Add New . Select the desired application from the Common Applications list. The
trigger port amd incoming ports will be automatically filled in. The following picture
takes application MSN Gaming Zone as an example.
4. Leave the status as Enabled and click Save .
Note:
• You can add multiple port triggering rules as needed.
• The triggering ports can not be overlapped.
• If the application you need is not listed in the Common Applications list, please enter the parameters
manually. You should verify the incoming ports the application uses first and enter them in Incoming
Ports field. You can input at most 5 groups of ports (or port sections). Every group of ports must be set
apart with “,”. For example, 2000-2038, 2050-2051, 2085, 3010-3030.
4. 7. 3. 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.
