Or Steffen could just add a tunnel to HE (https://tunnelbroker.net)
or one of the other tunnel providers.  I've been using HE for the
last 12 years.

Just about every application he is running is trying IPv6 then after
getting network unreachable going on to try IPv4.

For the record it isn't the zone.  It's enabling IPv6 locally without
having a working upstream link.  You would get that message without
the zone being configured.
