Webfiltering - Subnet

zeus1976
Hello Together,

I've found a few days ago that it is possible to access from a DMZ address to the web server on the LAN.

There is no firewall rule and after several tests, I recognized that the proxy server (web filter) allows this access.

Policy Helpdesk confirm that is allow.

Can I prevent this?

Thanks for the feedback.

Best regards

    All you need is: ^https?://192\.168\.200\.[0-9]+\.

    That approach is useful if you have the non-guest LAN also using a Transparent instead of a Standard mode.

    Cheers - Bob
