The neutron-server service exposes the Neutron API to users and passes all calls to the configured Neutron plugins for processing. By default, Neutron is configured to listen for API calls on all configured addresses, as seen by the default bind_hosts option in the Neutron configuration file:
bind_host = 0.0.0.0
As an additional security measure, it is possible to expose the API on the management or API network. To change the default value, update the bind_host value in the [DEFAULT] section of the Neutron configuration located at /etc/neutron/neutron.conf with the management address of the controller node.
