Cannot connect to Content Porter 2013 SP1 with multiple bindings set

Question

I am having issues with my Content Porter 2013 SP1 client connecting to the Tridion CMS server. My error is 'Could not find SDL Tridion Content Manager server...'. However, I can connect to the same server with the GUI.

We have 2 bindings in IIS: - loalhost - url based

Fiddler gives me "HTTP/1.1 500 System.ServiceModel.ServiceActivationException"

We did not have this problem with the Core Service in Tridion 2011.

I installed it with the Google ClickOnce tool and it saved the local ContentPorter 2013 SP1 files here: C:\Users\UserName\AppData\Local\Apps\2.0\8BKMWX5H.E77\HHPXJGL0.8LX\cp.a..tion_cefdd28298bce0cb_0003.0004_dcbe3a7bb47e778a

And, I have a cp.exe file there, and also an interesting /config folder with 2 files inside: - system.servicemodel.bindings.config - system.servicemodel.client.config

I found this binding and tried the URL in a browser, but get the .Net default YSOD page:

<endpoint name="ImportExport_basicHttp_f6a43d3b-941b-4d72-8e45-621761653bef" address="http://dev.tridion-server.com:80/webservices/ImportExportService2013.svc/basicHttp" binding="basicHttpBinding" bindingConfiguration="ImportExport_basicHttpBinding_http" contract="Tridion.ContentManager.ImportExport.Client.IImportExportService" />

What are the next steps for troubleshooting? I have the feeling my Core Service on the server is not working well.

Event Log:

    WebHost failed to process a request.

     Exception: System.ServiceModel.ServiceActivationException: The service '/webservices/ImportExportService2013.svc' cannot be activated due to an exception during compilation.  
The exception message is: This collection already contains an address with scheme http.  

There can be at most one address per scheme in this collection. If your service is being hosted in IIS you can fix the problem by setting 'system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled' to true or specifying 'system.serviceModel/serviceHostingEnvironment/baseAddressPrefixFilters'.

The answer is in the error message:

If your service is being hosted in IIS you can fix the problem by setting 
'system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled' to true or
 specifying 'system.serviceModel/serviceHostingEnvironment/baseAddressPrefixFilters'.

WCF never allows to have two endpoints in a service model configuration with the same scheme (http, net.tcp, etc.). My recommendation would be to only have the localhost endpoint as endpoint configuration and to let IIS handle incoming requests from other machines.
