Even with IPv6 you still might have stateful firewalls allowing only for outbound connection at both ends (e.g. a CPE a.k.a. “WiFi router”) and to establish communication you’d need to punch a hole in those firewalls.
That’s true we won’t get rid of hole-punching with IPv6. But at least it will get rid of TURN.
How will it get rid of TURN? Can't IPv6 addresses still be firewalled by your carrier like they do already for IPv4?
The hole punching is so much simpler because you don't need to guess your own address and port - you just know it
Doesn't that assume that your machine is given its own world-routable (and unfiltered) v6 address?
