[ovirt-users] [ovirt 3.6] Logical network not working

[Marcin Mirecki]

Hello Luca,

The description of your setup seems to be correct.
Can you please disable firewalld and iptables just to make sure this is not the cause.
I'll try to recreate and see what the possible causes can be.

Thanks,
Marcin
