Transparent proxy?
Are the clients connecting through the proxy?
Example of what you are trying to filter/block and if logs say something about it?
IIRC webproxy filter can block domains but it’s not set to analyze url requests…
There are protocols and other things that can be blocked through IPS module.
EDIT:
The proxy can be enabled only on green and blue zones. Supported modes are:
- Manual: all clients must be configured manually
- Authenticated users must enter a user name and password in order to navigate
- Transparent: all clients are automatically forced to use the proxy for HTTP connections
- Transparent SSL: all clients are automatically forced to use the proxy for HTTP and HTTPS connections
The proxy is always listening on port 3128. When using manual or authenticated modes, all clients must be explicitly configured to use the proxy.
clients can be
automatically configured using WPAD protocol. In this case it is useful to enable Block HTTP and HTTPS ports option to avoid proxy bypass.
If the proxy is installed in transparent mode, all web traffic coming from clients is diverted through the proxy. No configuration is required on individual clients.
In transparent SSL mode, the proxy implements the so-called “peek and splice” behavior: it establishes the SSL connection with remote sites and checks the validity of certificates without decrypting the traffic.
