Your setup might sound secure to you but there are some smart people out there
Spoofing a MAC address only is really feasible if you know a MAC address thats on the whitelist already. If you want to brute-force it... I imagine that would take some time.
Of course since MAC addresses are given out in blocks to device manufactures you could narrow down a brute-force search a bit. Ie someone allowed on the network has an iphone, so you already know the first 4-6 digits of a whitelisted MAC address, which leaves 6-8 others... around 16^6 possibilities at the best case.
It can be done, of course, but someone would have to be very dedicated.
