Answer: Deny anonymous users access

Longer Explanation

In order to automatically redirect non-logged in users to login page, you need to deny anonymous access to "all" pages. This is done in the site's web.config file:

web.config

   
      ...
      
         
      
   

The special ? token is used to represent anonymous users.

This, when combined with telling Forms authentication where the "Login" page is:

   
      ...
      
         
      
      
         
      
   

means that any any anonymous users will be automatically redirected to the login page.
