Of course, I realize the need to go to IPv6 out on the open Internet since we are running out of addresses, but I really don't understand why there is any need to use it on an internal network. I have done zero with IPv6, so I also wonder: Won't modern firewalls do NAT between internal IPv4 addresses, and external IPv6 addresses?

I was just wondering since I have seen so many people struggling with IPv6 questions here, and wonder why bother?
