21.1. OpenVPN General¶
OpenVPN implements virtual private network (VPN) techniques to create secure point-to-point or site-to-site connections.
The VT AIR allows the creation of OpenVPN Servers and OpenVPN Router Clients.
For a secure site-to-site connection, one site needs to have a OpenVPN server configured and the other one a OpenVPN router client. To get a working connection, both sites need to be configured with the same device mode, authentication mode, encryption algorithms, digest algorithms and tunnel network.
