Abstract
Described are techniques to establish an on-demand, secure, point-to-point tunnel between a source device of a source network to a target device of a target network. The target network may not be visible to the source network. The target network includes a tunnel client and a tunnel server may be a perimeter device of the source network. The tunnel client may send a first message to the tunnel server. Data may be transmitted from the source to target device by including the data in a return message in response to the first message. The first message and the return message may be sent over one or more “heartbeat” connections which are continually established and torn down to transmit data between the two networks, and the source and target devices therein.
