This is why I stick with root firewalls -- I also use a VPN, and I don't think you can have your Android device use more than one VPN at a time (without rooting it).
Pretty much all "no root firewalls" work the same way.. The software pretends to be a VPN client in order to get the network traffic and filter it.
Since you're letting the software have control over all your network traffic, make sure you trust the software manufacturer.
