UPnP is short for Universal Plug and Play. 

This function enables the router to open port automatically for UPnP-based programs. 

It is generally used for P2P programs, such as BitComet and AnyChat, and helps increase the download speed. 

To access the configuration page, log in to the web UI of the router, and choose More > Advanced > UPnP.

This function is enabled by default. When any program that supports the UPnP function is launched, you can find the port conversion information on this page when the program sends any requests.
