This is a supplement post on setting and configuring OpenVPN. However, we are going to configure OpenVPN on a Raspberry Pi. Download and Install Raspbian OS Download the latest Raspbian OS and burn the image to a SD card using the software Etcher. Once we booted up the Raspberry Pi, we can follow the wizard to set password, enable wifi and update the software. We can also choose to enable ssh and vnc using Raspberry Pi Configuration software. We can also run the configuration software from command line using raspi-config.

If you are still using an old image of AWS and you have already installed Openvpn then the following setting may still work.
