Thank you Miguel, my openstack is working fine on ESXi. But when I try to<br>
do the same things with my openstack installation on real servers it<br>
doesn't work. I'm still stuck with br-ex problem and the vlans in which my<br>
interfaces are. br-ex can't reach the outside because eth0 is in a vlan.<br>
any idea<br>
