Howdy,
I’m going to apologize in advance if this is a simple question, but my google-fu is not getting me results.
I have a 3D printer. This printer allows me to connect it to my local network so my PC can send it files. I can see it attempting to communicate out to the internet via my PIhole however. How can I block it from attempting to reach out but still allow it to connect to my PC?
Consumer thing: if you are running a fritzbox router: there is a checkmark in the network tab for the device to block internet access for it.
this also works for Asus routers
