The NAT66 draft enables NAT to rewrite the IPv6 header in a "checksum compatible" way. NAT66 don't have to go fetch the UDP or TCP header and whack the checksum. That is certainly a simplification, but it comes at a cost. Since there is a simple mapping between internal and external subnets, the external addresses carry information about the internal topology. How is that as a tradeoff?
