NAT is not a security feature.
Thank you!!
If you don't want your devices to be accessible from the internet, you want a firewall. Treating NAT like a firewall is a bad idea.
But still, if I understand correctly, with NAT you can just use one firewall for your router and with IPv6 you'd need a firewall for each of your devices. This seems like a lot more to manage, right? But maybe I still don't understand the concept of IPv6.
Edit: Apparently I don't understand the concept of IPv6.
That's not correct, but it shouldn't preclude you from applying defence in depth.
Firewall and NAT are separate concepts. You can still have a firewall on your router when using IPv6. I don't know how many consumer-grade routers handle it well though.
