Connecting to Visual Studio debugging IIS Express server over the lan

I have a test ASP.NET MVC3 application developed in VS2012. When I start debugging the app is accessed from the host machine via the request to http://localhost:<portnumber>. But if I try to access the same application from the remote machine in the intranet via the http://<ip>:<portnumber> I get HTTP error 400: Bad request. Invalid Host Name. As far as it runs on IIS Express any server configuration is inaccessible.
