Cyrus with mac-restriction

That doesn't make it much clearer. You know that MAC addresses are only 
visible in a local subnet, right? Why don't you restrict access by IP 
address? I have a hard time imagining a reasonable scenario where what you 
ask for is necessary ... that's why I was asking what you're trying to 
achieve.

To answer your original question, I don't think there is any mechanism that 
allows for restricting access based on MAC address. Certainly not within 
Cyrus, possibly using iptables or such.
