Nuget feed behind IIS reverse proxy not working

Hi,

I am using IIS as a reverse proxy. It is working as expected except for the Nuget feed. The <Content> element for the package url is still showing as localhost:8080 instead of the public host. Does anyone know how to fix this?

I also have the following error on the Nuget settings page.

"NuGet Feed must contain server URL inside. Current TeamCity server configuration does not let TeamCity server to get original request URL from HTTP request. It looks like TeamCity server is wrongly configured with reverse proxy. Make sure reverse proxy and TeamCity server is configured to let TeamCity server know request real request URL"

The feed used to work correctly. I think it broke on the upgrade from version 7 to 8 (currently running 8.02).

My web.config rewrite rule is as follows

<rule name="ReverseProxy-teamcity" stopProcessing="true">
    <match url="(.*)"/>
    <action logRewrittenUrl="true" type="Rewrite" url="http://localhost:8080/{R:1}"/>
    <conditions>
        <add input="{HTTP_HOST}" pattern="teamcity.svr-it"/>
    </conditions>
    <serverVariables>
        <set name="HTTP_ACCEPT_ENCODING" value=""/>
        <set name="HTTP_X_FORWARDED_HOST" value="teamcity.svr-it"/>
        <set name="HTTP_X_FORWARDED_SERVER" value="teamcity.svr-it"/>
        <set name="HTTP_HOST" value="teamcity.svr-it"/>
        <set name="SERVER_NAME" value="teamcity.svr-it"/>
    </serverVariables>
</rule>

The Teamcity Server URL is set to http://teamcity.svr-it

Any ideas to fix this would be appreciated, thanks.
