Iis – TeamCity Nuget feed via IIS/ARR/URLRewrite

Versions:

• Windows Server 2008 R2 SP1
• TeamCity 7.0.2
• Tomcat 7.0.27
• IIS 7.5
• ARR 2.5
• URL ReWrite 7.2.2

TeamCity is installed into a pre-existing TomCat installation as a JavaEE WAR.
IIS has been successfully setup to reverse proxy calls for TeamCity. My rewrite rule is below:

<rule name="TeamCity Redirect" stopProcessing="true">
    <match url="^(TeamCity.*)" />
    <action type="Rewrite" url="http://localhost:8080/{R:1}" logRewrittenUrl="true" />
</rule>

I have no problem logging into TeamCity from a remote host and using/administering it.
However, when I enable the built-in NuGet server, I encounter a frustrating issue.

Trying to access the nuget feed from any remote host proxying through IIS gives me an HTTP 404 error. The 404 error comes from IIS. When I remove the final path part from the url, the 404 error comes from Tomcat.

Example:

• http://proteus.pointloma.edu/TeamCity/guestAuth/app/nuget/v1/FeedService.svc from any host gives an provided IIS 404 error.
• http://proteus.pointloma.edu/TeamCity/guestAuth/app/nuget/v1/ from any host gives a TomCat 404 Error.
• http://localhost:8080/TeamCity/httpAuth/app/nuget/v1/FeedService.svc from the server where TeamCity is installed provides the feed correctly.

So, somewhere I am having issues with IIS respecting a redirect with *.svc files, but for the life of me, I cannot figure out why, or where this is set.

Any help is greatly appreciated.
