Some clients on network changing their browser's Proxy From "192.168.1.1" to another external proxy ...

Hi,

either block this site on ISA or prevent them to change proxy setting using GPO, for example.

Regards,
Paulo Oliveira.

The real problem is that you have your edge firewall configured to allow HTTP traffic from everywhere instead of just from ISA.  If you restrict access to ISA, then people HAVE to have the proxy settings correct or else they can't get out to the web.

Explain how to change your edge firewall?  No, I don't know anything about your configuration or your organization's policies.  You should talk to your firewall administrator about the problem and tell them that you need to limit outbound HTTP/S access so it can only be allowed to originate from the ISA server.

I suggest you try another web filter. As I know this porn filter is not bad. It has password protection, which can not be bypassed by using web proxies without password. You can  add unwanted websites to blacklist with this porn filter.
