IPv6 means no more NAT? I think a lot of people will still put networks behind NATing firewalls just for some 'security by obscurity'. If IPv6 means everyone just plugs every server, workstation and device up to the internet directly, oh boy... going to be a lot of job security for network security experts
It mean NAT is no longer needed. You can still set one up if you need to for some reason, though, in my opinion, a better solution is just a home router that firewalls incoming connections. You'd just configure it with what ports you want open on what host, kind of like port forwarding, but where every host gets a unique public IP so that you can "forward" the same port for two hosts.
