Abstract
A method is performed at a mesh access point (MAP) of a mesh network in which MAPs are configured to communicate with each other over wireless backhaul links. The method includes: receiving, from a first wireless client having a first client address, client traffic destined for a second wireless client having a second client address, the client traffic including a first source address that represents the first client address, and a first destination address that represents the second client address; generating a first obfuscated source address that differs from the first client address; replacing the first source address in the client traffic with the first obfuscated source address; and transmitting the client traffic with the first obfuscated source address in place of the first source address to a next MAP of the MAPs over a wireless backhaul link for subsequent forwarding to the second wireless client.
