A system and method establishes bidirectional contact through firewall devices. A method includes establishing a first connection between a first device and a second device and storing a connection record on the second device. When the second device receives a request to connect with the first device, it identifies and searches for the connection record corresponding to the first device. When the second device finds the connection, the second device sends a request to establish a second connection from the second device to the first device. Upon receiving the request to establish a second connection, the first device verifies the request to establish the second connection and the lifetime of the first connection. Upon verification, the first device establishes the second connection between the first computing device and the second device.
