About this question
I'm wondering how to use NAT with IPv6. Seems that you don't even need it any more. So what exactly is the concept behind firewall configurations in IPv6 environments?

Biggest issue to me in removing NAT is the reduction of privacy. With IPv6 I notice all my LAN devices have a unique public IPv6 address, which allows each device on a LAN to be identified uniquely. Which then allows easier identification of individual devices and users.
Privacy implications like the ability to track your activity across domains. Ad providers obviously do this type of tracking already with cookies, but removing ipv6 NAT makes their job easier to track an individual device.
