squid configuration : ACL's based on MAC address

There are many times that client are having dynamic ip address (assigned by DHCP server) and in this cases it's hard to set any rules on bases of ip address as, you would not know what ip address the client machine be getting, in such case we could use mac based ACL's to set up any rules on that particular machine.

 # vi /etc/squid/squid.conf 

Look for acl section and append ACL as follows:

acl mac1 arp 00:11:22:70:44:90 

acl mac2 arp 00:11:22:33:44:55 

http_access allow mac1 

http_access allow mac2 

http_access deny all 

Save and close the file.

Restart squid server:

# /etc/init.d/squid restart
