Yes,I don't understand why Neutron needs enable ip_forward and disable RPF. And I also don't understand where the neutron need this config during the instance connect to the extrernal network.
I read the neutron code, found when the L3 agent creating, it needs the ip_forward config,but i'm not find the RPF config in the neutron code.
