Hi,
We have a squid server running which looks into user access. Now there are users who would use a webproxy or a external proxy to bypass this restriction. Is there a way to stop them.
One rule is to figure out all the proxy sites and address and feed them to blocked sites but that process doesn't look good and easy manageable. Any suggestions ?
Hi Sachin,
Use squid as a transparent proxy. Using iptables, redirect all requests for port 80 to port 3128. On your firewall/router, block access to the internet from all workstations except the squid box.
