Dynamic virtual private network
First Claim
1. A method, with a first virtual private network (VPN) device in a remote network, for establishing a site-to-site VPN between the remote network and a private network, the method comprising:
- receiving a VPN request from a client device within the remote network to establish a VPN connection with the private network;
analyzing local VPN information for VPN information associated with the private network;
determining, based on the analyzing, that the local VPN information fails to comprise VPN information associated with the private network;
establishing a VPN connection with a central system through a public network in response to the local VPN information failing to comprise VPN information associated with the private network, wherein the central system is situated between the first VPN device and a second VPN device in the private network, where the first VPN device is local to the remote network and the second VPN device is local to the private network;
receiving, from the central system and based on establishing the VPN connection, a set of VPN information associated with at least the second VPN device;
disconnecting, based on the receiving, from the central system; and
establishing, based on the set of VPN information, a site-to-site VPN directly with the second VPN device through the public network, wherein one or more client devices within the remote network communicate with the private network utilizing the site-to-site VPN through the first VPN device.

Abstract
Various embodiments establish a virtual private network (VPN) between a remote network and a private network. In one embodiment, a first system in the remote network establishes a connection with a central system through a public network. The central system is situated between the first system and a second system in the private network. The first system receives, from the central system and based on establishing the connection, a set of VPN information associated with at least the second system. The first system disconnects from the central system and establishes a VPN directly with the second system through the public network based on the set of VPN information.
