Solution to require approval for new network devices
I’m trying to find a solution that will allow me to detect and authorize any new devices being added to my home network. Ideally I’m looking for a non-subscription service that I could run on an existing system or a standalone raspberry pi box. Seems like all of the “network protection” devices/services out there are all subscription based and focus on things like vulnerability scans, malicious site blocking, etc but none seem to offer a simple option to prevent any new device connecting to my network until I approve it from my phone.
Thanks in advance for any suggestions
