I’m just curious, what if I’d use my pi-hole to block all connections from/to China on my home network. I have a good bit of automation in place, but mostly western solutions, yet still I wouldn’t be surprised if they called China. Have any of you tried this kind of experiment? Is it even possible to block? What gone down?
I use pfsense which has geoip blocking, however this is only going to be a threat if you have open ports, most if not all firewalls are default deny, so what I do is only allow North America and South America (family there).
I might suggest just looking at crowdsec.
