An end-to-end virtual private networking system transports network packets securely through a public data network. A mobile device comprises an application client and a wireless roaming client managing data transfer from the mobile device to the public data network via one of a plurality of predetermined wireless links. A roaming gateway is located in a data center and is coupled to the public data network for tracking the plurality of predetermined wireless links and for managing data transfer from the public data network to the mobile device via one of the plurality of predetermined wireless links. An enterprise server is provided in a private enterprise for exchanging network packets with the application client in the mobile device. A CPE-VPN router in the private enterprise network is coupled to the enterprise server and to the public data network. A VPN router located in the data center is coupled to the roaming gateway and to the public data network, wherein the VPN router and the CPE-VPN router establish a VPN tunnel therebetween via the public data network. The CPE-VPN router transports the network packets between the enterprise server and the VPN tunnel. The VPN router transports the network packets between the roaming gateway and the VPN tunnel.
