When your washing machine, fridge, etc all come with ipv6 5g modems is when your house becomes part of the future IT battlescape between lots of different entities that do not wish you well.

I’m assuming you don’t know how iPv6 works. With SLAAC every device usually rotates the v6 address every few hours and maintains multiple of these. Each subnet for each customer is huge. With rotating MAC it’s virtually impossible to maintain a connection with an IPv6 only device by just IP address. It’s one of the features of IPv6 that such attacks are not going to be feasible.
Why? My router won’t even let me DMZ a single ipv6 device or open all ports to a single ipv6 device. It will only let me open one port at a time.
different routers have different options, but all of them have come with a pretty strong firewall out of the box, turned on by default, for the last 10 years.
No, because sensibly configured routers would still block incoming traffic regardless of NAT.
