Hello everybody!
So here’s the situation. I have a smart home KNX technician from Fiverr who would like to access my smart home controller remotely to configure things for me. The thing is that I don’t fully trust this person, and I would like to give them a VPN access only to that specific device on one specific UDP port (3671). I would like to prevent them from accessing other devices on my network, and routing their traffic through my network (in case they have some malware, and my network would start some attacks).
Is it possible to be achieved with ZeroTier? I don’t have any advanced networking equipment only basic ISP router (so no VLANs).
Thank you in advance for your help.
