Anyone who's into and Smart Home devices should learn just enough about networking in order to place each device on its own little Class C subnet; so that your smart bulbs, TV, vacuum, and other appliances only see themselves on the network and nothing else.

@oedmarap It's a good idea but doing it well comes with real challenges. They should be on separate VLANs - simply overlaying multiple IP networks on the same layer 2 segment provides little to no security benefit. And what if you want to control a device from your phone or computer? Such devices usually rely on multicast/mDNS, so now you have to set up multicast routing. I think there's an opportunity here for a consumer router/AP that does all of this magically.

@christopher Yeah, I can imagine a proper setup would have to be thorough.

What about using something like a separate ISP line (I know, I know...) and an SDWAN a la Tailscale as an overlay network?

I know it's a lot of round trips but that should be sufficiently secure, and should also address the direct/dynamic DNS and device control issues?

But yeah, a router that has a prepackaged setup would be nice. I bet Ubiquiti has some model that already does that type of voodoo. 🙂
