How can I ping from destination A to destination B with my laptop? (I'm sorry that I have no network knowledge..)
Explanation:
ECU A and ECU B is connected via eth line.
I can access ECU A via ping test. (ECU A is connected with OBD cable and I can check with ping test) (EX: ping X.X.X.X is success)
I need to access ECU B via ECU A. So I want to check how I can ping to ECU B via ECU A with my laptop (EX: ping X.X.X.X to Y.Y.Y.Y )
If 3 step is success, I will try to access SSH to ECU B.
If this kind of trial is not right, please correct me.
Yes,
Use SSH or something to be able to access the destination A machine. After that you can ping Destination B from A. The same applies from B to A.
