Techniques are provided for transmitting data securely across virtual private network (VPN) connections. A first VPN connection is initiated between a first device and a second device. The second device selects a first communication protocol to be used for the first VPN connection with the first device. The first device generates session identification data associated with the first VPN connection and sends the session identification data to the second device over the first VPN. The second device receives the session identification data and stores it. The second device determines when the first VPN connection has been disrupted. The second device then selects a second communication protocol and initiates a second VPN connection using the second communication protocol with the first device. The second device transmits the session identification data to the first device, and the first device associates the second VPN connection with the first VPN connection using session identification data.
