I read a lot of fantasy about NAT-PT those days, like it is going to be the
silver bullet that will make this all problems go away...
NAT-PT is a v6 to v4 translator. Which mean, it only helps if your internal
network is... v6. If you have any device in there that cannot do IPv6 and
need to talk to the rest of the universe (think IP-webcam, gaming device,
windows box prior to vista, load balancer, IDS, firewall, IMS, xyz
server,.... NAT-PT is *not* a solution for you. Nor would be any of its
Dual-stack lite (see
http://tools.ietf.org/html/draft-durand-dual-stack-lite-00) might be a
better approach in that space. It is being standardized by IETF in the
softwire working group.
