Edge reversal tunnel proxy for isolated network

An apparatus comprising:

• a tunnel module configured to create a tunnel connection between a port of an edge server and a port on a cloud server, wherein the cloud server is unable to establish a communication link with the edge server independent of the tunnel connection;
• and
• a proxy module configured to initiate a proxy on the edge server, wherein the cloud server is configured to initiate a proxy on the cloud server in response to creation of the tunnel connection and wherein each proxy is configured to receive a message from a port and to transmit, over the tunnel connection, a modified message that includes a port number and the message, wherein the port number is a destination port number and wherein each proxy is configured to receive a modified message over the tunnel connection and to transmit the message contained in the modified message to the port identified by the port number in the modified message,
• wherein transmitting the modified message comprises formatting a header of the received message to include the destination port number to create the modified message, and wherein receiving the modified message comprises reading the port number in the header of the modified message.

A program product comprising a non-transitory computer readable storage medium storing code, the code being configured to be executable by a processor to perform operations comprising:

• creating a tunnel connection between a port of an edge server and a port on a cloud server, wherein the cloud server is unable to establish a communication link with the edge server independent of the tunnel connection;
• and
• initiating a proxy on the edge server, wherein the cloud server is configured to initiate a proxy on the cloud server in response to creation of the tunnel connection and wherein each proxy is configured to receive a message from a port and to transmit, over the tunnel connection, a modified message that includes a port number and the message, wherein the port number is a destination port number and wherein each proxy is configured to receive a modified message over the tunnel connection and to transmit the message contained in the modified message to the port identified by the port number in the modified message,
• wherein transmitting the modified message comprises formatting a header of the received message to include the destination port number to create the modified message, and wherein receiving the modified message comprises reading the port number in the header of the modified message.
