I would recommend not using a VPN App but a VPN router instead in conjunction with your internet router which gives you more flexibility. Do not use free VPN services as most will limit the speed and have issues. Go with a good VPN Service such as Pure VPN. The goal would be is to setup routing in your Internet Router to route certain IPs to the VPN router instead of your Internet Gateway. For example you would tell your main router to route your stalker IPs through the VPN router. This would let your other Kodi plugins use your main Internet and your live TV goes through the VPN. If you place an app on your box you loose this control and everything will go through the VPN. If you like this idea, you still can do this using a VPN router by setting up the network settings on the box to use the VPN Router instead of the Internet Router.
