Migrating from PFSense to OpenBSD

I have been running PFSense for 3 years or so and have been quite happy with it. It’s a decent software project that I encourage you to checkout, if you haven’t already. However, after some neglecting my home infrastructure, it was time to give it some time and love. Looking through alternatives for PFSense, OPNSense , a fork from PFSense, has been an attractive option with a much saner architecture than PFSense.

That said, I don’t really need a GUI for my router as I am much more fond of simple configuration files, and a secure edge point to the Internet. OpenBSD checks of a lot of desired boxes for an edge router, with it’s impressive security track record and networking features. All I really need is to manage a WAN and a LAN interface, DHCP and DNS. For wireless I run a TP-Link TL-WDR4300 with OpenWRT , so no need to fiddle around with wireless networking.

The router itself is in a small form factor case and completely silent. It sports a Gigabyte GA-N3050N-D3H mainboard with passive cooling, a Intel Celeron N305 1.6 GHz Dual core, 4 GB RAM, and a 128 GB SSD, which is more than plenty for a home router.


I need my edge router to do the following:

  • WAN to LAN
  • DNS for internal services/hosts (e.g. device.lan)
  • DHCP with static MAC mapping
