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?
Some more details may help here.
What printer is it and what’s it reaching out for?
As said, setting up static ip and removing the gateway will usually be enough. Vlans are the better option but steeper learning. I’d be interested to find out what it’s doing though. Knowing what you’re working with may help others advise you more specifically.
If it’s checking to find time or for updates then it’s probably harmless. Do you need internet to enable any features like remote send or monitoring and the like?
