The ETS cannot connect to the logic machine

Hello, thanks for answering. I don't understand why they say it's public? In the end I am making a LAN without Internet access, why does the logic machine block them? and how can I do to solve that. I say this because the client has other equipment (BMS servers, fire panels, cameras, AACC) with those same network configurations and I cannot tell him to modify them or the other equipment. Thank you and I look forward to your responses.
