Opnsense on a cheap fanless PC. I use a QOTOM box I bought of Alibay, which has a core i3 and 4 ethernet ports, but any mini-PC is good. Doesn't even need to be a mini-pc, but why use full desktop power for something that can be small and lightweight. It's run for years happily and comes with all the usual open source goodies out of the box. Good choices and GUIs for just about everything you'd want, all the way up to being able to run multiple of them for HA if really want to. The biggest impetus for me was the ability to have two cable connections (Frontier fiber and Spectrum cable) and setup failover and QoS across them. That's pretty hard on "normal" router hardware. Works well with Unifi APs too. If I redo it I'll probably go and get a newer box with mutliple 2.5G connections. Frontier offer 2Gb and 5Gb fiber here now, so would be nice to be able to get closer to filling that, but that's just the geek in me. Family never complain with everything as is over standard gigabit ethernet and WiFi.
