A network routing system is provided that may establish a communication session between a local device and a remote destination. To establish a communication session, the local device generates a message directed to the remote destination. A traffic processor intercepts the message and redirects the message to a predefined network server in a secure fashion. The network server receives the message, and extracts the address for the remote destination, as well as message data. The network server has a pool of available virtual address that are registered with the network server. The network server associates a virtual source address with the real address of the local device or traffic processor, and opens a communication session. The virtual address is set as the source address for the message, and the message is sent to the remote destination. Since the source address is virtual, the real address for the local device or traffic processor are not sent to the remote location. If the remote location sends a return message, the return message will be directed to the virtual address. The network server receives the return message, and using the virtual address information, redirects the message to the real address for the traffic processor in a secure fashion. The traffic processor sets the address on the message to show it was sent from the remote destination, and forwards the message to the local device.
