I'm following discussions about the IPv4->IPv6 transition, and IPv6 doesn't seem to like NAT at all.
I've always thought that NAT was helpful in v4 for some security, I know it doesn't really hide the computers but it makes them harder to get to, certainly it makes it easy to limit access to ports on the computers behind the NAT gateway.
The IPv6 contention is that it doesn't provide security, that real firewalls and gateway routers should be used instead. I don't like the idea of my entire home network being exposed on the internet.
So, is this a good or bad thing?
