Correct. That's why I'm suggesting it will go over routers. However, it is out-of-band because the sender and receiver are operating on their own. They both operate with regular traffic pushed to it by the operating system + apps running, but they are also operating in this way outside of that by issuing / responding to requests on the out-of-band traffic.
The OS and apps would never know a machine is being queried by vPro. They would keep on running like normal. It's all happening at a layer invisible to any security software running on the machine. That's my point. Best regards, Rick C.
