OK, thanks for the advice. I haven't grasped how IPv6 works completely
yet. So, NAT66 is for prefix rewriting, right? Where would I need that?
Simple routing (as I tried to achieve) doesn't work here?

I just stumbled over https://wiki.freebsd.org/IPv6TODO. Would you
recommend to wait with what I am trying to achieve? I mean, the VPN works
for IPv4, so I can let the servers communicate via v4 and not v6. Does
that have any disadvantages? I mean, shouldn't we all get IPv6-ready?

Thanks for sharing your experience.
