Require login on the total website?

I am setting up an internal forum which should only allow logined users to view all the posts.
What should I do to make each page redirected to the login page if not logined?
Thanks

The easiest way is to setup your forum permissions that the Guest group cannot access and read any of your category's. To do this you go to your category management select the category and uncheck all guest permissions under the permissions tab.

Thanks. it works.
But how can I show a prompt which says "Please login" instead of an blank page?
