SQUID

Hi, I installed the SQUID rpm. Set the SQUID startup at boottime option to "yes" (rc.config) Configured my squid.config so that connections on port 3128 are possible. Connected myself to the internet. Restarted SQUID so my changes in squid.conf will be active. Configured the proxy settings in my browser.... And ..... I try to connect to an internet page with my browser.. I receive the SQUID page telling me that I'm not allowed to go to that address. "Access Denied" Does anyone know what I did wrong???? Greetings Joris.
