Squid with mac address filter acl

I am setting up Squid proxy with mac address acl. I have recompiled squid 3.5 rpm with --enable-arp, acl. But after configuring Squid.conf with mac address acl its unable to block access for unwanted mac address. Is it possible to create iptable rule and allow some mac addresses to permit web access? if yes how to do that? --- **Edit**: Added as follows: acl mac arp 00:E1:34:CD:C0:22 http_access allow mac http_access deny all
