The pfSense & OPNsense Playbook: Practical Firewall, VPN, and High-Availability Patterns That Work.
Firewalls don't usually fail because of attacks. They fail because of complexity, drift, and changes no one fully understands.
If you've ever hesitated to touch a production firewall, feared an upgrade window, or inherited a ruleset nobody wanted to own, you already know the problem.
The pfSense & OPNsense Playbook: Practical Firewall, VPN, and High-Availability Patterns That Work is written to fix that problem-systematically, practically, and permanently.
This book shows how to design, deploy, and operate pfSense and OPNsense as long-lived, production-grade systems. Instead of screenshots and surface-level configuration tips, it focuses on how traffic really flows, how state and routing actually behave, and how to build firewalls that survive upgrades, outages, growth, and human error. Every chapter is grounded in proven patterns used in real environments, from single-site networks to multi-WAN, high-availability deployments.
You'll learn how to build segmentation that scales, write firewall rules that don't collapse under change, design VPNs that remain stable under load, and operate HA pairs without guesswork. The book goes beyond setup and into operations-observability, troubleshooting, automation, upgrades, and rollback-because that's where most failures happen.
By the end of this playbook, you'll be able to:
Design firewall architectures that remain stable as networks grow
Implement NAT, routing, and VPNs with predictable, testable behavior
Operate high-availability firewalls without fear of split-brain or downtime
Troubleshoot blocked traffic methodically using packet capture and state analysis
Plan upgrades, rollbacks, and maintenance with confidence
Treat pfSense and OPNsense as engineered systems, not fragile appliances
Written in a clear, developer-focused style, this book is ideal for network engineers, DevOps practitioners, sysadmins, and developers who want firewalls they can reason about, trust, and change safely.
If you're ready to stop guessing, stop firefighting, and start running firewalls that work exactly the way you expect-this playbook belongs on your desk.
