NAT Forwarding
Tips:
•  It is recommended to keep the default settings of Internal Port and Protocol if you are 
not clear about which port and protocol to use.
•  If the service you want to use is not in the Service  Type, you can enter the 
corresponding parameters manually. You should verify the port number that the 
service needs.
•  You can add multiple virtual server rules if you want to provide several services in a 
router. Please note that the External Port should not be overlapped.
Users on the internet can enter http:// WAN IP (in this example: 
http:// 218.18.232.154) to visit your personal website.
Tips:
•  The WAN IP should be a public IP address. For the WAN IP is assigned dynamically by 
the ISP, it is recommended to apply and register a domain name for the WAN referring 
to  Set Up a Dynamic DNS Service Account. Then users on the internet can use  
http:// domain name to visit the website.
•  If you have changed the default External Port, you should use  
http:// WAN IP: External Port or http:// domain name: External Port to visit the website.
10. 2.  Open Ports Dynamically by Port Triggering
Port Triggering can specify a triggering port and its corresponding external ports. 
When a host on 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 and Quick Time 4 players, etc. 
Follow the steps below to configure the Port Triggering rules:
1. Visit http://tplinkwifi.net, and log in with your TP-Link ID or the password you set for 
the router.
2. Go to Advanced > NAT Forwarding > Port Triggering and click Add.
Done!
