Once you have Squid and DansGuardian set up, the final step is to implement a transparent proxy using iptables. Use the following commands at the command line to add rules to the firewall to allow the user squid to access both the Internet and the Squid proxy we set up.
Since we have a proxy server set up, a user could configure a Web browser to bypass the filter and access the proxy directly. The Squid proxy is listening for requests from the computer, and it doesn't care which user sends the request. We could set up our firewall to deny all access to the proxy except from our filter, but let's be a little sneakier. Let's set it up so that direct requests to the Squid proxy server, except from our filter, get redirected through the filter. To do this, use the following command:
