FWaaS v2, implemented as a Neutron service plug-in using OVN port groups and ACLs, supports stateful layer 3/4 rules, per-tenant policies, and router-level policy assignment. The guide covers enabling FWaaS in Red Hat OpenStack Services on OpenShift 18 FR4+ via a patch to the OpenStackControlPlane CR, creating firewall rules and policies, and attaching them to router ports. Best practices include combining FWaaS with security groups for defense-in-depth, using stateless SGs alongside FWaaS due to a known compatibility issue, standardizing on FWaaS v2, and enabling logging for observability. ## Full article daily.dev links to this article rather than hosting it.
