Айболит-66

Ну что, кто страдал без NAT в IPv6? Любой ваш каприз за ваши деньги. Встречайте: NAT66

P.S. "the IETF does not recommend the use of NAT"(c). Хоть кто-то меня поддерживает.

P.P.S. Раздел "Motivation" прекрасен:
"We are documenting NAT66 because we believe that some people will
choose to implement and deploy IPv6 NAT, in spite of our
recommendation not to do so.....Our goal is to define an IPv6-to-
IPv6 NAT mechanism, NAT66, that will minimize the negative impacts of
IPv6 NAT, in the event that some implementers do choose to implement
an IPv6 NAT mechanism, and some network administrators do choose to
deploy it."
