Just wondering what the difference between setting up a VPN through a 4g hotspot and connecting 3 rigs to it, vs VPN through each of the 3 rigs and leaving the hotspot with no VPN. Anyone know?

Currently trying to set up just the hotspot with a VPN, but the rigs don't get internet then .. but this is probably a restriction from android/verizon.

Has anyone here tried to get a VPN shared through a hotspot? Any easy workaround with verizon/android?
