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.
