I think Marco is referring to a tweet I made, but I did not mean to say
that the VPN breaks. It does not. It's just the VPN pre-empts the DNS64,
and since only specific (my) IPv4/IPv6 networks are pushed by the VPN,
this means that I can no longer reach IPv4-only content on the internet
(IPv4-only content in my own network works fine, through the VPN, and
all IPv6 content is also fine - through the VPN for my own networks, or
directly for the rest of the internet).

I didn't try contacting the OpenVPN server through the NAT64 (native
IPv6 in both the server and client end now), but I could try that as
well. I don't expect it to fail though, so unless you hear anything to
the contrary, assume it worked fine.
