My current setup runs OPNsense on an x86 machine with 2.5Gbps ports (as an LXC inside proxmox), whereas the one in my post only has 1Gbps ports. But the location of it isn’t great for wifi, which is why I want to use this separate machine for wifi only. So there’s really no need for me to do firewall etc. on this one, I really just want something that can do VLAN’d wifi networks.
I also use opnsense on a mini pc as a firewall, works great :)
Seems that using it for WiFi is a little iffy based on most of these comments though. The guide you linked also didn’t cover much info about hardware, and I can’t see VLAN-support either, so maybe I should just give in and buy a ubiquity one instead.
Doesn’t seem to be what I’m after but thanks for sharing
