NAT Forwarding

12  1   ALG

ALG allows customized Network Address Translation (NAT) traversal filters to be plugged 
into the gateway to support address and port translation for certain application layer 
“control/data” protocols such as FTP, TFTP, H323 etc. It is recommended to keep the 
default settings.  
You may need to disable SIP ALG when you are using voice and video applications to 
create and accept a call through the router, since some voice and video communication 
applications do not work well with SIP ALG.

, and log in with your TP-Link ID or the 

password you set for the router. Go to

12  2   Set Up Public Services on The Local Network by 

Virtual Servers

Virtual Servers are used to set up public services on the local network. A virtual server 
is defined as an external port, and all requests from the Internet to this external port 
will be redirected to a designated computer, which must be configured with a static or 
reserved IP address. When you build up a server on the local network and want to share 
it on the Internet, Virtual Servers can realize the service and provide it to the Internet 
users.
The table displays the relevant parameters of the virtual server. 
To set up a Virtual Server rule:
1. Visit 

http://tplinkwifi.net

 or 

http://192.168.0.1

, and log in with your TP-Link ID or the 

password you set for the router.
