Hello friends:

Good Day!!!

I have CentOS 6.6 server installed with Squid proxy 3.5.1 recompiled source RPM with --enable-arp \ & --enable-arp-acl \ options, which are required to enable mac address filtering acl.

I want to allow internet access to only allowed mac addresses via squid. I have tried with below ACL in squid.conf but its not blocking other mac addresses.

acl allow_mac arp 01:23:45:AB:E0:CC
http_access allow allow_mac
http_access deny !allow_mac <======This is to block other mac address

Also let me know if this is possible with iptables.

I need to block internet access to some users but they should able to access samba share on the server.

Please help me to resolve this issue,

Thanks in advance.
