	there are many other ways to solve case A, including:
	- IPv6 PPP over TCP (can penetrate any NAT as it is TCP)
	- RFC2893 tunnelling with certain NAT/decapsulator configuration
	if you wish to limit solutions to teredo and UDP tunnels, you would
	need to describe why.

	therefore, it is too early to conclude like this.
