Do you mean the stuff defined in RFC 3513 section 2.5.5?  I don't think
anyone's routing that.  I think the mechanism was even obsoleted by
another RFC.

Perhaps you are referring to the NAT-PT described in RFC 2766, which is
obsoleted by RFC 4966.

In either case, I don't think this will work as you think.
