Why does documentation recommend adding VPN3k/ASA MAC address to the CAM as a "never-certified" "floating device"?
Suppose we have a NAC Appliance in In-band L3 mode behind a VPN 3000. What parameters does it use to identify clients? IP-address? MAC-address? Both? How does it choose if it has both L3 multihop clients and L2-adjacent clients?
If it uses IP addresses it can successfully differentiate between all the clients and the concept of "floating device" doesn't apply, right?
Is the identification of client devices performed uniformly for a) user authentication b) posture assessment c) Nessus scanning? (Note that Certified Devices list seems to only have MAC-addresses of adjacent devices, whilst Online Users list contains both MACs and IPs).
Also, even if it doesn't know MAC address of the remote device, Clean Access Agent (and Web Agent) are able to send it to the NAC Appliance, right?
Please shed some light on this.
