Unfortunately that isn't the issue as the docker bridge is 172... and
bridge0 is 192.168... so they don't conflict. Also docker0 doesn't
seem
to have any devices (meaning it brctl show has no interfaces attached
to it). Finally shutting down docker and removing docker0 doesn't
restore connectivity, only a reboot does. Not even restarting NM
fixes
the issue.
Try running 'iptables-save' before you start docker, and then running
'iptables-save' after. Diff the results. Did docker remove anything?
