Abstract
Techniques for high availability of virtual private networks (VPN's) are provided. VPN gateways are organized as a virtual ring of VPN gateways. A client seeking to establish VPN communications with a destination resource is assigned one of the VPN gateways as a primary gateway and one VPN gateway as a secondary gateway. When a client's primary fails, the client seamless transitions to its designated secondary and the VPN gateways reconfigure themselves to account for the primary's failure.
