so we were wondering why internet access was so slow at our apartment
-> turns out IPv6 doesn't go through the router the way it should
-> turns out that is because there is an IPv6-specific iptables chain that is created for ip6 filter FORWARD with policy DROP, which supersedes my own nftables chain
-> turns out that is because docker, in the year of our lord 2024, still feels the need to create its own forward chains in the iptables system and without minding nftables, and specifically forbids ipv6 forwarding

i just want to grab a docker dev and ask them what the fuck at this point
