Thank you all.

So, Ubiquiti is a very interesting solution indeed, but my network is pretty much as I want it now - except for the firewall of course, and I'd guess a Ubiquiti firewall device would make little sense in a non-Ubiquity network, right?

OpnSense and pfSense both look really great. Protectli Vault hardware is *very* nice too.

I'll try to make my mind between NetGate/pfSense vs Protectli/opnSense .

What I am mostly concerned about is that the firewall does not end up being a bottle neck on a 1Gbps fiber optics data link. So, while Netgate offers some official throughput data there, I am not sure (yet? still educating myself) about Protectli/opnSense; I am sure there is Protectli hardware to offer all power I need, but I can't yet figure out what I'd need and its cost, while with Netgate/pfSense I know.
