I am also working on getting that proxy on my mobile working properly. For the reason that my mobile has become my main internet connection. This is cheaper and the internet is a lot faster via my mobile. I have a VPN client on my mobile and I want to add a firewall, because I want to be able to keep an eye on what data is going out. But I quickly came to the conclusion that declines say Don't attract the VPN. That's why I bought the server Ultimate app to use proxy. I can barely find any documentation on how to properly implement this.
