Are you aware of the security implications?  Unless you route the relevant
gateway prefixes yourself, you will be using a 6to4 gateway which can be
anywhere and belong to anyone, subject to the whims of BGP anycast.

That's why IPv4 is preferred over 6to4, in fact.

(unfortunately, I don't actually know how to increase the preference of
2002::/16, as you already tried gai.conf and that didn't do it).
