title: WCF service blocked by Windows Firewall
body: <p>I've got a WCF service using a HttpBinding. The service is running in a self hosting process (A Windows Service) and this process is inside the Windows Firewall exceptions list.</p>
  
  <p>If the Firewall is active and I'm trying to access the service using a C# client or Internet Explorer, the service does not respond. But if the Firewall is disabled the connection works like a charm.</p>
  
  <p>Does anyone have expirence with WCF and the Windows Firewall? The problem came up on Windows 7 64bit. I didn't try another OS yet.</p>
  
  <p>What am I supposed to do to get this working with an active Firewall?</p>
  
  <p>Regards Michael</p>
  
  <p>EDIT:
  I found a clue, that the http.sys has to be added to the firewall exceptions list, as wcf self hosting uses http.sys. Any advices, how to solve this?</p>
  
  <p>EDIT: 
  I tried opening all listening port manually, which works too, but is not an option, because I don't know them in advance.</p>
