Haha, no not really. IPv6 has the ability to provide public IP address for each device, but that doesn’t mean it will have to. Other than number of possible addresses, nothing is different. Routing, firewalls, NATs, etc. All remains the same.
IPv6 doesn’t support NAT… Or am I woefully out of date.
But your home router will just firewall like it does already but you don’t have NAT as a simple fall back for “security”. It does make running internal services much easier as you no long need to port forward. So you can run two webservers on port 80 and they be bother allowed inbound without doing horrible load balance or NAT translation.
IPv6 has NPTv6, which allows you to translate from one prefix into another.
Useful if you’ve got dual WAN, and can’t advertise your own addressing via the ISP. You can use NPTv6 to translate between your local prefix and the public prefixes. But NPTv6 is completely stateless. It’s literally a 1:1 mapping between the prefixes.

IPv6 has both NAT66 and NPTv6. (Yeah, it’s confusing.) NAT66 is more like the traditional stateful NAT that all of us know and understand.
