A question about data flow.

Coder68
When I turn off the proxy, and go out to the net, I see the firewall rule for web surfing get listed as being hit, when looking at the live firewall log. 

When I turn on the proxy, and repeat the experiment, I do not see the firewall rule being used. 

I turned off the rule to allow web browsing, and left the proxy on. I could still browse the net. 

I am also wondering where the logic for app control comes in. Below is my expectation of how this flows.

Is this flow diagram correct?

{See modified image at the end of the thread}

If not, can you please help me to make it correct?

Thanks,
C68

    In Transparent, the client sends the browsing request to the IP of the FQDN in the URL, and the Proxy captures the request because it's using port 80. 

    In Standard mode, the client sends the request to the IP of "Internal (Address)" on port 8080, and the Proxy requests name resolution for the FQDN.

    Cheers - Bob
