OK… I figured out how to get OpenVPN Client setup for DietPi.
Step 1
Set up your OpenVPN Server
Step 2
Login as root on to your DietPi
Step 3 Type-
apt-get update
Step 4 Type-
apt-get install openvpn
Step 5 – Configure the OpenVPN Client
In /etc/openvpn/ create a new text file named – (Your sever name).ovpn
Paste this text in - PLEASE MAKE CHANGES-----
How to setup OpenVPN client?
1. Install OpenVPN software on your platform.
2. Double click XXXX.ovpn file to create new connection profile.
3. Type username and password while connection.

-----BEGIN CERTIFICATE-----
(THIS IS LOCATED ON YOUR SERVER CALLED YOURSERVERNAME.CA)
-----END CERTIFICATE-----
Step 6
Copy your CA from the server to the client
On the client - located at - /etc/openvpn/client/
Step 7 Type-
service openvpn restart
Step 8 (Just to make sure you have connectivity on both sides)
On the client, try and ping your server
Step 9 Type-
openvpn --config clientname.ovpn
Step 10
Enter your user name and password
Step 11
When OpenVPN shows the message “Initialization Sequence Completed“, then you are connected.
