NPS + mac authentication

Hello,

Since 2 weeks, I set up 2 SSID. One for visitors open for internet, and one for employees, with authentification group based on radius + NPS.

Unfortunalety, we have equipements who are using wireless to work.

And now, we can't using them because the employee wireless is secure by user authentication.
For these kind of equipement, I want to set up a third wireless based on mac authentication.

For example, my equipement have this mac AA:BB:CC:DD:EE:FF, and when I connect to this third wifi, the adress mac is know and allowed to access the wireless

Do you know what are the rules I need to use for this ?

In NPS here is what I configured :

In Conditions : 

- NAS port type : Wireles - IEEE 802.11

- NAS identifier : EXAMPLE

- Calling station ID : AA:BB:CC:DD:EE:FF

In constraints : 

Authentication methods : Unencrypted authentication (PAP,SPAP)

In settings :

Filter ID : 100

Framed protocol : PPP

Service type : Framed

it is going to work ?

Thank you
