Cannot Connect to Interent from the TMG Server.

HI All,

 I need to update the Windows directly from this DMZ TMG Server.

 External Nic: No  DNS Server and Set the DGW

 Internal Nic: No DGW and Set the LAN DNS servers

Rule: create Internal to external Access Rule for HTTP/HTTPS 

 IE: Select Automatically detect settings

 But i cannot connect to Internet?

 Localhost/Internal web proxy enable but Port set to 8080

I can see External NIC got Internet but i cannot connect to Internet to update the windows?

or browse the internet? ( error:IE cannot display the website)

As
