An <b>OpenVPN client</b> is an entity that initiates a connection to an OpenVPN server. To create a new client instance, go to the <i>Services → VPN → OpenVPN</i> section, select <i>Role: Client</i>, enter a custom name and click the 'Add New' button. An OpenVPN client instance with the given name will appear in the "OpenVPN Configuration" list. A maximum of six OpenVPN client instances are allowed to be added.

<b>Stunnel</b> is an open-source a proxy service that adds TLS encryption to clients and servers already existing on a VPN network. TLS encryption provided by Stunnel can be used as an additional layer of encryption for data sent by VPN. This procedure increases the security of the established connection and provides higher chances of passing a Deep packet inspection (DPI) check.
