What did you do to disable filtering but still have Dans Guardian running and passing traffic. I am experiencing the same problem you are describing. I was wondering if you disabled via the conf file did you try re-enabling items a few at a time to see if any one feature was causing the problem? I am actually using Apache as the proxy and that does work normally if I connect directly to it so I know that is not the problem. The problem seems to be DansGuardian not passing the traffic through to the proxy correctly.
