Hi,

Not sure that was tested with VLANs, and I don't think there has (yet) been any work to create and OpenVSwitch based firewall driver. Have you seen specific problems with packets getting around the firewall rules when using openvswitch?

I know there were plans for making an OpenVSwitch firewall driver, but there are some big performance issues around rule explosion. I don't think there is anything penciled in for Folsom right now.

I will get in touch with the networking experts and get back to you.

Thanks,
John
