So what I say is: <v4 world> - <NAT> - <tunnel over v6> - <process NATed v4> And what you say is: <v4 world> - <NAT> - <translate to v6> - <forward over native v6> - <translate to v4> - <process NATed v4> Your model has more steps, and it's also more complicated. If you know you're going to go back to v4 anyway, it makes more sense to keep the IPv4 header around and tunnel rather than translate. This doesn't affect the IPv6 processing, because all IPv6 header fields can be the same regardless.
====> Iljitsch, I¹m afraid you characterization is oversimplified. Would you like to have an off-line conversation (phone or maybe at the next NANOG) to go over the details? - Alain
