Unless you put a application/protocol translation in the middle IPv6
can't talk to IPv4. yahoo("IVI","Ecdysis NAT64") for two possibilities
one have for that, oh and yahoo("IPv6Gate") for a ready-to-use HTTP
specific one.

But if you didn't know that fact, you might want to invest in a proper
book about IPv6 and read up quite a bit. As this is NANOG, a good
operational book is "Running IPv6".
