Hello,

I now how i can configure de Transparent proxy on the XG. Create a Firewall Policy, define a WebPolicy an Thats it.
System can access through the Configured Proxy by Browser an access tha internet without Proxy on the browser.

But how i can configure the Access to the Internet like on the UTM.
I want to configure that Systems cant access the Internet directly.
But configuring the proxy settings on the Browser could work.

On the UTM that was pritty simple.
