Current UPNP
Rule Listing
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses
TCP/IP for simple peer-to-peer network connectivity between devices. A UPnP device
can dynamically join a network, obtain an IP address, convey its capabilities and learn
about other devices on the network. In turn, a device can leave a network smoothly
and automatically when it is no longer in use.
These are the rules the Router has created using UPnP.
External Port
This is the external port number that identifies a service.
