Abstract
This disclosure provides methods and techniques of performing source network address translation (SNAT) at a packet sender (e.g., a client device) instead of a gateway device (e.g., a proxy device). The present disclosure performs a SNAT operation at the packet sender, relieving the gateway device from the SNAT operation to perform other duties (e.g., policy enforcement). An example method of network address translation includes modifying, by a processing device at a data packet origination device (e.g., a client device), network address information in an internet protocol (IP) header of a packet using a public IP address. The method further includes sending the packet to a public network based on the public IP address.
