I need to setup a site that will have users accessing it from the Internet, as well as Admins from the Intranet. I need to deny all Admin rights when a user is accessing from the Internet.  In fact, I would prefer that you not even be able to login from the Internet with an Admin account.  THis may not seem logical, but it is imperative that Admin access cannot be achieved from the internet.  My current application (non-Nuke) is split into two different sites to ensure Admin access cannot happen, but I would rather it be just one.

There is not a way to configure DNN to do this with the UI.

But, you could do this by modifying the SignIn.ascx.vb file located in the admin/security folder.
