Abstract: Described embodiments provide systems and methods of forming overlay tunnels for delivery of data between networked devices. A first intermediary device may transmit, responsive to a connection request from a client, a request having a source IP address corresponding to a first virtual IP address of the first device and a first payload including first security hash information to be processed by a second intermediary device. The first device may receive, from the second intermediary device, a response. The response may have a source IP address corresponding to the IP address of the server and a second payload including a virtual IP address of the second device, responsive to second security hash information corresponding to the first security hash information. The first device may establish an overlay tunnel using the first virtual IP address and the second virtual IP address for communicating data between the client and the server.

Abstract: Described embodiments establish at least one secure connection for a session. An intermediary device may intercept a domain name service (DNS) request from a client. The device may determine, according to the intercepted DNS request and configuration data of the device, that the client is preparing to establish a session with a server. The device may send a client hello message of the device to the server for establishing a first secure connection between the device and the server for the session, prior to the client sending a client hello message of the client for establishing a second secure connection between the client and the device for the session. The second secure connection may be established between the client and the device using a specified value for a session identifier received from the server in response to the client hello message of the device.
