HTTPS Filtering

Hi!

I don't know how to ask this question but I am really stuck on this.

I am trying to configure TMG on windows server 2008 for HTTP and HTTPS Filtering.

I have routed all internet traffic to my default route on L3 300-28 (TMG Server interface e.g. 192.168.0.1).

e.g. IP Route 0.0.0.0 0.0.0.0 192.168.0.1

e.g. I have configured Vlan 10 (10.10.10.2 255.255.255.0 GW 10.10.10.1)

Now on the Client Computer

When I browse the HTTP traffic without proxy settings, it work fine HTTPS do not work. BUT when I put the proxy settings in the browser It could not open no HTTP nor HTTPS.

Any body help me to understand how to do that?
