lxc container public interface (eth0) is bound to vmbr0 and private interface (eth1) is bound to vmbr2.I removed the post-up/pre-down lines from the containers, it was a left-over when i tried to fix the issue. It doesn't change anything, public and private network works well, except between the containers. So i can talk to anything outside the host, but not inside.Le 09/07/2016 à 12:33, Alwin Antreich a écrit :Guillaume, On 07/09/2016 12:10 PM, Guillaume wrote:What is your intention with the post-up?
