PPTP VPN Android with Auto-Reconnect capability

Question

Android

Greetings.
Tell me if there is software for using PPTP VPN on Android 4 with the ability to:
* Connect at device startup
* Reconnect when disconnected, change network, ...
* Block traffic through non-VPN
(Well, or at least auto-reconnect when disconnected)

It is PPTP that interests you, search , unfortunately, gives out more anonymizers configured on their servers

Answer 1

VPNRoot - PPTP - Manager
, alas, it only works if there is a root
, I also did not find analogues :(
