@Thomas, can you try 'brctl stp br0 on' in the VM?
I reproduced your setup using an lxc container connected to a bridge, and a separate network namespace inside the container. With stp off, I could not ping the host or the outside world (without setting routes). With stp on, I could ping the host, ping google.com, and ssh to other laptops on the same subnet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/684424 Title: Bridges are not transparent for packets -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
