I want to route my home wan ip adress over my vpn
You cannot do this.
If you route your WAN IP address via the tunnel then the tunnel breaks. This is because when openvpn tries to send encrypted VPN packets to the server for decryption, thus providing the VPN, those packets are sent into the tunnel which then routes them into the tunnel and they never go to the server.
It does not work for Android either. Android sees that the packets are being sent to the tunnel and not the server and then over-rides your broken route and sends the packets to the correct destination.
