NAT is really firewalling at all. It just accidentally implies a "default block new inward" policy, which any good actual firewall setup for IPv4/IPv6/other would have as a default anyway.

Were it not for home routers supporting NAT because they need to with IPv4, the same routers would have a basic firewall with that default block rule in place.

I think you meant 'isn't', and we're in agreement. It is just that it has some of the same effects.

Yep, small accident between the brain and the typing fingers there.
