Hi!

The patch in the ticket solves the problem, but there seems to be another with IPv6 NAT.
I found a way to get around the IPv6 NAT, so this is not urgent to me anymore, in the
hope, that this error has also something to do with IPv6 NAT ;-) Perhaps there is a better
place to report this. If you have an idea?

Nevertheless, here is the laster iteration:
