vWorkspace 7.5 Secure Gateway/WebAccess

Hi,

I'm having trouble configuring Gateway and WebAccess role on the same server. I'm able to go to the HTTPS://remote.domain.com from WAN, but then I get redirected to the HTTP:// / , which is internal LAN server name unknown to the WAN, I get "page cannot be found". Internally it works fine, but users will complain that site is not secured. I attached screenshoot of the Secure-IT. What am I doing wrong? I watched all the videos on how to setup secure gateway but it did not help me. Is there is a detailed document on how to setup and configure Gateway?
