I have an external site that works great and has anonymous access enabled. I can view everything on the site that is by default accessible by anonymous users. When I click the login page I get this: Error Code: 403 Forbidden. The server denied the specified Uniform Resource Locator (URL). Contact the server administrator. (12202) I wanted to be able to login using standard methods, ie using my windows active directory credentials. We do not want external users to access the site but I personally want to be able to access it from the internet so I can add/remove things as I see fit. I haven't found a good article out there on how to publish an anonymous access site through TMG 2010. I have followed the Technet article to a T but have not been successful getting the login page to work. Like I said, everything else works fine. It also works fine internally, so I figure it something wrong with TMG/sharepoint communication.

How did you set the client authentication method and authentication delegation on Forefront TMG? Please refer to http://technet.microsoft.com/en-us/library/cc995255.aspx Gu Yuming TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.com

I tried everything but first I followed the article about how to publish a sharepoint website through ISA 2006 since TMG and ISA are very similar and TMG was just the step up from that. http://www.isaserver.org/tutorials/How-to-Publish-Microsoft-Sharepoint-Service-ISA-Server-2006.html I did not use SSL, I tried HTML forms selected Windows AD, NTLM Authentication and configured that on the sharepoint server as well. I just want a comprehensive article on what is needed from the TMG server and the Sharepoint server to make it work. I tried everything under the sun honestly from the TMG server and nothing worked.
