Access to Visual Studio Team Foundation Server over the Internet

Question

We have a TFS 2010 environment with SharePoint 2010. We want this to access it over internet. We would mostly want user to provide access to TFS2010 Web Access URL from internet. And, the users could then be able to see(create) work items, Source control. Once they click to the Report and Project Portal they should be re-directed to relevent sites.

I have found follwing link-

Has anyone implemented it.

Thanks upfront.
