How do I have openVPN only be the connection between client/server rather than the devices main connection?

[DonBigly]

So I have the openvpn setup "working" and I can connect from client to client and all that. But the problem is the openvpn connection becomes the devices (turtle and connected computer) MAIN connection. I only want it to be a tunnel where all other traffic will route as usual on the client device.

You can perhaps look at how the Packet Squirrel OpenVPN payload is used. It has two "modes" that sounds similar to what you seem to want to achieve.
