I am installing Squid 2.6STABLE on CentOS 4.4. I want to have our Mikrotik router DST-NAT all port 80 requests to it and use it as a transparent cache. Anyway I am hung up on access control. This was easy on Mikrotik integrated cache. #allow my IP pools on port 80 src-address=12.1.1.0/24 dst-port=80 action=allow src-address=12.1.3.0/24 dst-port=80 action=allow #deny all else action=deny How do I accomplish this in the Squid config? Also, if I DST-NAT all port 80 traffic to the linux box Squid is running on do I need to config anything special in the Linux kernel? Thanks. Matt
