Have you ever looked at your ISP-provided router and thought, “I wonder what it would be like to build my own firewall?” That’s precisely what went through my mind last year when I finally made the switch from an ISP router to my own DIY networking solution. Although no beginner when it comes to building custom firewalls, having built a few pfSense units in the past, I never attempted it at home because I never had the need. Even with network-attached storage (NAS) and a powerful PC at the ready, I still didn’t feel the need to make the switch.
