I have a Lennar built smart home and it comes with Commscope Ruckus hardware ICX-7100 router and 610 wifi AP. I was wondering if there was a good firewall UTM solution by them or if I should repurpose a dual nic I7-5000 series mini PC and run Sophos NG or Untangle ?
I would suggest opnsense ( provided it's supported by your hardware) . Then you can install snort (Ids/ips), pf-blocker ( ad-blocker) and so many other apps like these for free.
