if NAT66 is an option
Can you define "NAT66" precisely?
We need the a box that translates local IPv6 addresses into global IPv6
addresses using a stateless NAT using a one-to-one reversible mapping
algorithm for single-homed edge networks. That is precisely what NAT66
as described in the draft does according to our understanding.
Clarification: when I say 'reversible', I mean that the translation
is reversible before the packet is delivered to the transport layer at
the remote end (as in 8+8/ILNP or SHIM6).
Ok, yes, we assume that feature in upgraded hosts, but not in classic
IPv6 host that may also be accommodated in a GLI domain.
Obviously, any NAT has to perform its local mapping in both directions,
but tha's not what I meant.
That was the meaning of "reversible" in the NAT66-mrw doc.

The only precise proposal I am aware of is
http://tools.ietf.org/html/draft-mrw-behave-nat66
(which I should stress is *not* an IETF WG document,
despite its name). That is a stateless, non-reversible
NAT.
