UPnP is a protocol that enables application running on a host to automatically configure port mapping on the NAT-Router. On the other hand, enabling UPnP may pose potential danger to network security.
There are three requirements for applying UPnP:
1. The device must be enabled with UPnP.
2. The operating system of the internal host must support UPnP.
3. The application must support UPnP.
