People have been asking for IPv6 Support on GitHub since years (probably a decade by now)
… and someone even got so annoyed that they decided to setup a dedicated website for checking this: https://isgithubipv6.live/
The word you are looking for is firewall not NAT.
No the word I’m looking for is the NAT. It was not designed for security but coincidentally it is doing the heavy lifting for home network security because it is dropping packets from connections originating from outside the network, barring of course, forwarded ports and DMZ hosts because the router has no idea where to route them.
Consumer router firewalls are generally trash, certainly aren’t layer 7 firewalls protecting from all the SMB, printer, AD, etc etc vulnerabilities and definitely are not doing the heavy lifting.
By and large automated attacks are not thwarted by the firewall but by the one-way NAT.

They are literally piggybacking on the netfilter module of Linux. I don’t see how that’s trash
They are not layer 7 firewalls for the network which are going to be where most the majority of attacks are concentrated. No citation needed unless you believe they are layer 7 firewalls or using something like Snort.
Added some clarification in my first sentence so it makes a bit of sense.
Wait, why are we talking about Layer 7 when NAT and firewalls are Layer 4 at best?
