NimbostratusI see no obvious security advantages of using MAC Masquerade either. Perhaps they want it to reduce L2 noise instead? When Masquerade is used, multiple originating BigIP (L2 Server-Side) MAC addresses will be contracted to just one. This adds to clarity on the wire as a BigIP middle-ware device is easily distinguishable from the other addresses, possible clients. To some extent, this will contribute to ease of sniffing, monitoring/surveillance. As a security enhancement, I don't buy the idea. As a security enhancement through added clarity, it might be a valid thing to ask for.
