Abstract:
Systems, methods, and computer-readable storage media are provided for managing application traffic. A routing policy defines the data flow path between the client device (which uses a virtual private network (VPN) client) and the appropriate network-based service. Based on various factors associated with the user, the client device, and the destination (e.g. network-based service), the routing policy will direct the VPN client to communicate with either a public DNS (via the public Internet) or to a private DNS (via the private Intranet). The resulting IP addresses will be used to establish a particular route (either over a public Internet or private Intranet) between the client device and the network-based service in accordance to the routing policy.
