This bp introduces a few enhancements to Firewall as a Service (FWaaS) API including making it more granular by giving the users the ability to apply the firewall rules at the port level rather than at the router level. Support is extended to various types of Neutron ports, including VM ports and SFC ports as well as router ports. It also aims to provide better grouping mechanisms (security groups and service groups) and discuss the use of a common
classifier in achieving it.
