Maybe through iptables somehow? You can usually arrange to restrict machine that connect to only those with specified MAC address on the connecting interface - whilst this can be worked around by someone clever they would need to spoof the known MAC address of one of the machine in your list - but it is safer than not having a restriction to only known MAC addresses HTH
