where value is one of:
n TUN (OpenVPN managed)—Also known as routing mode. Each OpenVPN client is
assigned a different IP subnet from the OpenVPN server and other OpenVPN clients.
OpenVPN clients use Network Address Translation (NAT) to route traffic from devices
connected on its LAN interfaces to the OpenVPN server.
n TAP - OpenVPN managed—Also know as bridging mode. A more advanced
implementation of OpenVPN. The IX20 device creates an OpenVPN interface and uses
standard interface configuration (for example, a standard DHCP server configuration).
n TAP - Device only— An alternate form of OpenVPN bridging mode, in which the device,
rather than OpenVPN, controls the interface configuration. If this method is is, the
OpenVPN server must be included as a device in either an interface or a bridge.
