Re: [ovirt-users] Associate IP addresses to MAC addresses (anti-spoofing rules)

Andre, The clean-traffic is meant to prevent mac/IP/ARP spoofing. I am afraid this is the best we can offer out of the box at the moment. If you are willing to give some additional effort you can try and look at the OVS based networking (added recently). You could use the vdsm hooks to create some additional openflow rules on the ovs-switch that would put some constraints on where the traffic is going. One more item which is still in a very early development stage is an OVN-provider (http://openvswitch.org/support/dist-docs/ovn- architecture.7.html). OVN itself is also still not a ripe project, but is actively being developed. If you are interested I could update you once we have something working.
