I am trying to control an industrial robot over 5G using 2x TRB500 gateways.
What is working: I can connect via public IP dirrectly to robot GUI and I can controll it.
PC (browser) + TRB500 — 5G — TRB500 (bridged mode) + ROBOT
Where I have a problem: I can not acess robot Modbus TCP server on port 502. It is blocked (at least nmap teest suggests it is firewalled). Can you sugest how to open port 502 to be forwared to my robot when TRB500 is in bridged mode?
