Let me explain - We have an external web site and on the Home page we have a login box. We would like to enter the login imformation and whenthe login button isclickedit logs in the user to an internal Sharepoint based intranet/or other web based intranet site. The login would have to go through a firewall to authenticate against the active directory on the internal privatenetwork. So basically you login and if you authenticate you get the internal intranet site without having to VPN in to the intranet. Any suggestions/help would be greatly appreciated. What ports need to be open, code samples, etc would be very useful. Thanks, JHeiser

I'd recommend you publish your site through an ISA-server which would let you do what you describe in your question.
