[Squid Filter] Error 403 and 404

  • Hello to all,
    I have 2 BOTH Firewall 2.3.2 (amd64) FreeBSD 3.10-RELEASE-P5

    The Objective is use Squid to filter (in this case Porno).
    With a firewall I receive PROPERLY Error 403 (OK Correct)
    The error on the other Firewall,and the 404 and it does not work a duty. I covered and reinstalled 3 services Squid:

    proxy server
    Reverse Proxy
    Guard filter Proxy

    But I'm not in charge, the settings seem identical on both machines.
    I guess we ARE something else What May cause the error.

    Help; D
