Hi. I've been trying to setup IPv6 in ROS. I managed to get it working a while back, but eventually something I did (not sure what) broke it. My config closely matches this guide, however, it still does not work, as I have no public IPv6 connectivity. Pinging ipv6 addresses from the router itself also does not work, as I get "no route to host." or a timeout (times out after a reboot, after ~15 minutes it switches to "no route to host.")
Here is my configuration.
The issue may be the following image, however, I am not sure exactly what that means or how to fix it. Any help would be much appreciated!

Seemingly resolved itself after plaguing me for days as soon as I made this post. Connectivity now works.
