Reading Modbus data through Port forwarding

I would like to read the Modbus data remotely without the data to server function.
I have an OpenVPN connection to my TRB143 and with the Modbus Client an Test request, i get the data. Now I would like to configure a Port Forwarding, so that i can read the data remotely just with the IP of the router an the port.
My read out program says “connected” but i don’t receive data.
Can somebody help?


Thank you for reaching out. I’d like to clarify how you intend to access the data. Are you planning to use a specific platform for data retrieval, or do you intend to read the data directly from the TRB143 web interface?


thank you for your answer.
When i logged in the next day, it was solved. I think my common carrier had problems.
