I want to isolate my 3d printer from my university network for safer operation while allowing me to remotely monitor its camera from outside the lab. Physical network equipment like a router is banned. I was thinking of setting up an OpenVPN server at my off campus home, and routing both the V1Pi raspberry Pis and my control tablets through there to introduce segregation. But, I don’t know if this gets me anywhere.
If I set up an OpenVPN tunnel using V1Pi’s built in Net Management Features, and its on, can people from the same physical connection (so randos at the university sniffing net traffic) still access the Pi connected to my 3D printer, or does the OpenVPN tunnel block local wired traffic?
