Abstract
A first packet is received from a client over an internal network destined for a remote node of an external network. The first packet includes a source IP address having an internal network portion that identifies a location of the client in the internal network and an external network portion that identifies a location of the internal network accessible by the external network. An obfuscation operation is performed on the internal network portion of the source IP address of the first packet to conceal the location of the client in the internal network and the internal network portion of the source IP address of the first packet is rewritten with the obfuscated internal network portion while maintaining the current external network portion of the source IP address. Thereafter, the first packet is transmitted to the remote node over the external network.
