We only use SSL on 443 and we only allow Squid to connect to TCP ports 80/443/21, so I have squid setup the following way: acl SSL_ports port 443 acl CONNECT method CONNECT http_access deny CONNECT !SSL_ports acl Safe_ports port 80 # http acl Safe_ports port 443 # https acl Safe_ports port 21 # ftp http_access deny !Safe_ports With this setup, any attempt to connect to a host on a port other than 80/443/21 will be denied. --- Chris Covington IT Plus One Health Management 75 Maiden Lane Suite 801 NY, NY 10038 646-312-6269 http://www.plusoneactive.com
