You’re way off on your comparisons. Routers that shipped with WPA3 had an IPv6 setting of “enable ipv6” and nothing else. Comparing it to a bygone era of no encryption is dumb.
On a router I had back in the day that seemed to only offer IPv6 support with a toggle of "enable IPv6" it still had a stateful firewall of all out and no new in by default, you just couldn't add custom rules because its whole legacy firewall UI was based around the NAT port forwarding.
I've never had a home router that just completely opened IPv6 to the world on my whole home network.
I’m not sure what you’re saying. That that checkbox enabled IPv6 and made all IPv6 capable devices behind the router accessible without any filtering?
You said “had”, so presumably people found out what a bad idea that is and routers added filtering without also introducing NAT for IPv6. Isn’t that exactly the point?
Yes, that’s exactly what they did. The assumption (presumably) was that anyone smart enough to browse the router settings would know to put firewalls on everything.
After all, the entire point of ipv6 was to allow connections to internal devices. If the router blocks it, what’s the fucking point? (See the dichotomy now between people who claim ipv6 stateful filtering for routers is obvious and the people who want ipv6?)
They eventually added in a default stateful firewall as well for ipv6, which made it completely pointless to convert. Still can’t host games without STUN, etc.
