I would like to link several Raspberry Pi devices with a computer running Ubuntu 16 using OpenVPN Community Edition. The ubuntu computer will be acting as the server and each of the pi devices will be remote data loggers which will connect to the server via the internet. The connection should be automatic upon boot and remain connected. If the internet is lost, the pi devices should automatically attempt to reconnect. Once connection to the server is accomplished, each Pi device should be assigned their own static ip address. I need to use OpenVPN Community Edition.
