Complete Transparent SQUID Linux Firewall Configuration
NOTE:
You have to copy paste the entire acl-final.txt file in squid.conf. Best is to paste at end of file.

1. edit your squid.conf. Add these acl..
acl mac1 arp 00:14:85:99:3B:8D
acl ip1 arp 192.168.0.1
2. Add this before "http_access deny all"
http_access allow mac1 ip1
using this way you bind mac with one IP address that user can’t change his machine address
to bypass squid filters.
NOTE: Squid can only determine the MAC address for clients that are on the same subnet.
If the client is on a different subnet, then Squid cannot find out its MAC address.
Sample:-
acl our_network src 192.168.0.0/24
http_access allow our_network
acl mac1 arp 00:14:85:99:3B:8D
acl ip1 arp 192.168.0.1
http_access allow mac1 ip1
http_access deny all
