He's mistaken that NAT always requires TURN. Consumer NAT typically still allows incoming UDP, using STUN/punch-through, or TCP with uPNP support. He maybe meant to talk about only about more restrictive NAT situations or campus/corporate/ISP/nation-state/scientology-compound firewalls.

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.

Hole punching in the context of webrtc is usually referred to as ICE.

UPNP has a number of functions, including forwarding of WAN packets to a specific LAN device.
