Using IIS to forward requests to internal websites

Microsoft IIS Web Server

I have some internal websites that I want to be accessible from the Internet. The servers themselves are not accessible and so I want to allow them to be accessed by providing access through a proxy server which sits in our DMZ. In orer to achieve this, I thought that I could use IIS 7 and URL rewrite but I am failing to get this to work and all attempts to access the sites via IIS results in HTTP Error 403.14 - Forbidden.

To take our helpdesk as an example, I have created this as an application within IIS on the proxy server (I tried this as a virtual directory as well, but that did not work either). I then have created a url rewrite rule which is set to match the pattern "/helpdesk/(.*)" and rewrite this to "{R:1}". When I test this pattern within IIS, it passes. When I use this url "" in explorer on the proxy server itself, I can access the internal website.

However, when I try to access the website by browsing from within IIS, or by tring "http://localhost/helpdesk/" on the proxy server, I get HTTP Error 403.14 - Forbidden. When I look at more detail on this error, I see "This error occurs when a document is not specified in the URL, no default document is specified for the Web site or application", but I can access the internal site via Internet Explorer from the proxy server without specifying a document.

Any thoughts?
