Assigning a source address to a data packet based on the destination of the data packet

An article comprising:

• a machine-readable medium for storing instructions that are executable by a client on a private realm of a network having public and private realms separated by an interface device, the instructions causing the client to;
• determine, before an application running on the client finishes building a data packet to be sent, if a destination address of the data packet corresponds to the private realm or to the public realm;
• retrieve, before the application running on the client finishes building the data packet to be sent, a public address of the interface device that is addressable from the public realm if the destination address corresponds to the public realm;
• retrieve, before the application running on the client finishes building the data packet to be sent, a private address of the client that is addressable from the private realm if the destination address corresponds to the private realm;
• assign, before the application running on the client finishes building the data packet to be sent, a retrieved address to be the source address of the data packet;
• and the instructions further causing the client to;
• install a software module on the client;
• and
• bind the software module to the public address of the interface device;
• wherein the public address of the interface device is retrieved via the software module.

In a network having public and private realms separated by an interface device, a client in the private realm comprising a memory which stores computer-executable instructions for use in sending a data packet through the network;

• and a processor which executes the instructions to:
• determine, before an application running on the client finishes building the data packet to be sent, if a destination address of the data packet corresponds to the private realm or to the public realm;
• retrieve, before the application running on the client finishes building the data packet to be sent, a public address of the interface device that is addressable from the public realm if the destination address corresponds to the public realm;
• retrieve, before the application running on the client finishes building the data packet to be sent, a private address of the client that is addressable from the private realm if the destination address corresponds to the private realm;
• and
• assign, before the application running on the client finishes building the data packet to be sent, a retrieved address to be the source address of the data packet;
• and further comprising instructions to;
• install a software module on the client;
• and
• bind the software module to the public address of the interface device;
• wherein the public address of the interface device is retrieved via the software module.

A network comprising;

• an interface device that controls data packet traffic between public and private address realms of the network;
• and
• an internal client on the private address realm;
• wherein the client;
• determines, before an application running on the client finishes building a data packet to be sent, if a destination address of the data packet corresponds to the private realm or to the public realm;
• retrieves, before the application running on the client finishes building the data packet to be sent, a public address of the interface device that is addressable from the public realm if the destination address corresponds to the public realm;
• retrieves, before the application running on the client finishes building the data packet to be sent, a private address of the internal client that is addressable from the private realm if the destination address corresponds to the private realm;
• assigns, before the application running on the client finishes building the data packet to be sent, a retrieved address to be the source address of the data packet;
• and
• the client comprises a software module installed on the client and bound to the public address of the interface device, wherein the public address of the interface device is retrieved via the software module.
