I got a new ISP recently and for the first time ever, a possibility of using IPv6 on a wired home network. IPv6 is still a novel thing in Finland in 2024. I started by dragging my Ubiquiti EdgeRouter X to as close to the present day as possible with the stock firmware, upgrading to 2.0.9-hotfix.7. Then I wasted a whole evening trying to fiddle with the IPv6 configuration in the config tree. The closest I got was that my devices got IPv6 addresses, but couldn't send packets through the router....
