Hello, We are using it in production since few years now, it works correctly. But, if you think it will be easier to debug, that will surprise me :) Openflow rules are hard to read, understand and debug. We tried working on a tool that help debugging such stuff (see [1]) which is partially used by the team, but that's far from perfect :( [1] https://github.com/openstack/osops/blob/master/contrib/neutron/br-int-flows-...

H, The OVS flow based Neutron firewall driver is long supported by the community and used by many operators in production, please check the documentation: https://docs.openstack.org/neutron/latest/admin/config-ovsfwdriver.html
For some details how it works please check the related internals doc:

Folks,
As we know, openvswitch uses a linuxbridge based firewall to implement security-groups on openstack. It works great but it has so many packet hops. It also makes troubleshooting a little complicated.
OpenvSwitch does support native firewall features in flows, Does it mature enough to implement in production and replace it with LinuxBridge based IPtables firewall?
