I've got 2 tunnels active. For one, the rDNS delegation works fine; when I change it, I see the changes show up on ns*.he.net in seconds. For the other, though, they never show up; no matter what I set it to, it saves OK, but ns*.he.net never return anything but NXDOMAIN's.
Now, the one that's working fine is years old, and the one that's failing was created earlier this week. Is there some expected >multi-day lag time before the DNS delegations start taking effect?
