I am trying to solve the following problem.
I have a TCP / Modbus device connected to the eth0 of my rasp. The wla0 interface is connected to a router with internet access.
Through a VPN (https://www.dynvpn.com) I am accessing by accessing my raspberry, this service provides me an IP, example 126.96.36.199 and through my PC (windows) with IP 188.8.131.52 I can access the rasp in different networks.
My goal is to access the device that is in eth0, any suggestions?
any suggestions are welcome!
