A mobile hotspot separates the traffic from your mobile device and the hotspot, so if you view for your IP while connected to VyprVPN, the mobile device shows the IP of the VyprVPN server you are connected to, while devices connected via the hotspot will show the IP assigned by the hotspot.
In order to have end-to-end VPN encryption, you will need to connect both your mobile device and other devices using the hotspot to VyprVPN.
