Abstract: Some examples relate to a pre-shared key based virtual private network. In an example, a VPN server generates a unique pre-shared key (PSK) corresponding to an identity of a VPN client. The VPN server creates a mapping between the identity and the unique PSK of the VPN client, and stores it in a database. The VPN server shares the unique PSK with the VPN client. In response to receiving an IKE packet comprising an encrypted identity of the VPN client, the VPN server decrypts the encrypted identity of the VPN client from the IKE packet to determine the identity of the VPN client associated with the IKE packet. The VPN server retrieves the unique PSK corresponding to the identity of the VPN client associated with the IKE packet from the mapping stored in the database. The VPN server establishes a VPN connection with the VPN client.

Abstract: Systems and methods related to a VPN controller are provided. In some embodiments, a first VPN controller is configured to establish a VPN tunnel with a client endpoint, wherein the VPN tunnel is established using an authentication process of the client endpoint, route a L2 request to a second VPN controller via an established communication tunnel between the first VPN controller and the second VPN controller by identifying a Generic Routing Encapsulation (GRE) header of the L2 request and based on the GRE header of the L2 request, directing the L2 request to a responsive L2 device accessible by the second VPN controller, receive an encapsulated L2 response from the second VPN controller identifying acceptance of the L2 request, and enable an electronic communication between the client endpoint and the responsive L2 device at least via the VPN tunnel between the client endpoint and the first VPN controller.
