The correct way is to create VLANs. Then use the router's firewall to prevent devices in the IOT network from reaching into your other networks. Not all consumer network hardware supports VLANs though.
- hnburnsy 4y agoThanks I meant the discovery on the IOT LAN or VLAN.I don't need Amazon knowing that I have a Tesla charger
- discardedrefuse 4y agoGotcha. You can never tell how an IOT devices is scanning your network. It could be passively listening for broadcast messages, or it could be actively scanning all the private subnets. So, you probably need an access point that can do "client isolation" or "layer 2 isolation". This would prevent clients on the same wireless SSID from talking to each other. For example, looks like the Ubiquiti access points can do it. https://evanmccann.net/blog/2021/11/unifi-advanced-wi-fi-settings#fnr4 https://evanmccann.net/blog/2021/11/unifi-advanced-wi-fi-set...
- hnburnsy 4y agoThanks for the great info.
- hnburnsy 4y agoMy separate router allows me enable 2.4 G which many IOT devices need but keep my main router at 5 G only.
- discardedrefuse 4y agoThat's a good idea when you're just working with what you might have on hand. But if you're buying something, consider going a step above consumer network gear. There you'll find wireless access points that let you configure multiple wireless SSIDs on mixed or isolated radios...all at the same time.
