I am using Squid as proxy server on network. there are several websites using HTTPS, that i want to block on certain number of nodes (DHCP nodes).
since i can block these sites using iptables, but nodes are on DHCP which will coz firewall restart and list that nodes ip address in excecption list every day.
Is there any other way to deny a certain number of nodes to block HTTPS.
In past i blocked it via adding a hosts entry on Linux Server
127.0.0.1 logmein.com www.logmein.com secure.logmein.com
but using this blocked all users from being access.
i also want to block ftp using squid or any other way, and one more concern is to block uploading from my network
