 Thanks for your thoughts ... I was slowly coming to exactly that
solution ...

  Then I think you're saying NAT is here to stay .. in which case how
exactly on a linux border firewall with internal ip4 and external ip6
does one NAT ?

  Do we build a ip4 NAT to ip4 - and then route that nat'ed ip4 to ip6 ?
