3.3. OpenVPN
Communications can be secured by OpenVPN, an open source virtual private network software.
Detailed “how to” guides and software are available at http://openvpn.net.
Note: The date and time settings of the ITS101 unit are important for the OpenVPN
connections, as an incorrect time and date setting can lead to an OpenVPN connection being
rejected. See section 3.4 for configuring the date and time.
The ITS101 runs the OpenVPN software as a client application and as such requires client
certificates and key files to be generated and copied onto the unit in order for the OpenVPN
connection to be established. This can be accomplished by navigating to the “openvpn
settings” page on the web service.
