IPv6 eliminating NAT

I just saw an IPv6 tweet where the guy said he set up IPv6 DNS entries for all his home machines. He can now connect to them directly from his office to any home machine. He was happy to eliminate NAT.

I realize that you don't need NAT when your computers can all have their own IPv6 address - but NAT does provide some safety - think about it:

Now anyone knowing those IPv6s can contact (hack) his machines that are now sitting directly on the internet. Kind of like going back to the mid 1990s. IPv4 NAT was keeping him safe from alot of hazardous traffic that will now hit each PC directly...

If you want a firewall, use a firewall. NAT is a red herring.
