I don't think we can implement a stateful firewall[1] now. Once connection tracking capability[2] is added to the Linux OVS, we could start to implement the ovs-firewall-driver blueprint. [1] http://en.wikipedia.org/wiki/Stateful_firewall [2]

Hi, It's an interesting feature. But just to understand, what do you blame to the actual implementation with iptables and linux bridge? The OVS release 1.11.0 implements a new feature calls 'megaflows' which reduce the number of kernel/usespace crossings. Actually, OVS neutron agent uses simple

The current implementation is fairly generic, the plan is to get it into the ML2 plugin. -Mike On Tue, Nov 19, 2013 at 2:31 AM, Kanthi P pavuluri.kan...@gmail.com wrote: Hi All, Thanks for the response! Amir,Mike: Is your implementation being done according to ML2 plugin Regards, Kanthi

Hi Kanthi, Just to reiterate what Kyle said, we do have an internal implementation using flows that looks very similar to security groups. Jun Park was the guy that wrote this and is looking to get it upstreamed. I think he'll be back in the office late next week. I'll point him to this thread
