Hi, after prevent connections directly to port 3128 for all other ip's (with iptables) and configured DansGuardian to use 127.0.0.1 - I will get following message from Squid : ERROR The requested URL could not be retrieved While trying to retrieve the URL: http://www.linux-it.net/index.php The following error was encountered: Forwarding Denied. This cache will not forward your request because it is trying to enforce a sibling relationship. Perhaps the client at 127.0.0.1 is a cache which has been misconfigured. Your cache administrator is bleonhardt@analytek.de.
