Running #nixos on a N150 mini pc as a router for ~6 months: reliable, efficient, and surprisingly capable. Setup notes + power quirks: https://blog.stark.pub/posts/n150-nixos-router/
N150 NixOS router, a guide

Research notes, technical explorations, and things I find interesting.

@perstark Nice summary, I also run NixOS on my home firewall. I noticed you are defining both ip and ipv6 with essentially the same nftables rules, have you considered or is there a reason you aren't using inet rules to only define them once?
@kraftnix thanks! Lack of knowledge, I did not know it was possible. But looking it up it seems real nice. Thanks for the comment!
