Im not sure about UDP hole punching and how it relates to WebRTC, i don't see it being talked about much. In general hole punching is a rare thing to hear, I cannot find much resources about it. And uPNP (Universal Plug and Play) sounds like its for device discovery in the same local network, so again, it doesn't sound related to webRTC, we can connect directly with each other on the same local network anyway.
