Source-destination network address translation (SDNAT) proxy and method thereof

A system comprising:

• at least one device including a hardware processor;
• the system configured to perform operations comprising:
• receiving a first message at a first node on a first network, the first message comprising a first source address corresponding to a second node on the first network and a first destination address corresponding to the first node, and the first message being destined for a resource on a virtual network;
• selecting an unused address in the virtual network for use as a second source address for a second message to be transmitted on the virtual network;
• translating (a) the first source address of the first message to the second source address in the virtual network and (b) the first destination address of the first message to a second destination address corresponding to the resource on the virtual network to generate the second message, the second message comprising the second source address on the virtual network and the second destination address on the virtual network;
• transmitting the second message on the virtual network toward the second destination address on the virtual network.

A method comprising:

• receiving a first message at a first node on a first network, the first message comprising a first source address corresponding to a second node on the first network and a first destination address corresponding to the first node, and the first message being destined for a resource on a virtual network;
• selecting an unused address in the virtual network for use as a second source address for a second message to be transmitted on the virtual network;
• translating (a) the first source address of the first message to the second source address in the virtual network and (b) the first destination address of the first message to a second destination address corresponding to the resource on the virtual network to generate the second message, the second message comprising the second source address on the virtual network and the second destination address on the virtual network;
• transmitting the second message on the virtual network toward the second destination address on the virtual network;
• wherein the method is performed by at least one device including a hardware processor.
