In the case of vPro, "out of band" means that it's using the same wires
(or frequency) that the NIC is connected/tuned to, but it's being
processed outside of the OS's. So before your software firewall even
sees the packet come in, the NIC consumes it and passes it along to the
vPro chip to be handled. Since these control packets are not TCP/IP and
not using the OS's networking stack, they can't traverse network
segments (routers) unless explicitly forwarded.
