Hello,
I have switched to a new network location, and my containers are not connected anymore over lxdbr0.
Containers that have macvlan networking work, but the default networking over lxdbr0 stopped working. I have searched this previous questions and there is something about docker blocking lxc’s networking. (although docker was installed from the beginning, lxc and docker coexisted for a while before this stuck)
Here is my iptables -L -n -v
