Query about using ethernet with airunit. Creating a network with pc? tablet?

Hi we’re trying to get a network connected that would allow us to use the airunit and mobile hotspot to connect our rover with a desktop/laptop/tablet combination.

Our system design at the moment:

rover plugs ethernet into air unit, we enable mobile hotspot on the herelink receiver, then connect to the mobile hot spot currently on the desktop/laptop.

Firstly is it possible to form a network between these parts?

the plan is to network share a folder on the rover that can be accessed on the desktop/laptop PC

Provided that’s possible here’s our problem.

We currently have a static ip on all parts on the 192.168.43.0/8 network.

We can ping from the rover to the air unit. (192.168.43.1)
We cannot ping from the rover to the desktop. (192.168.43.111)

Any help would be appreciated.

Thanks

Nathan
