i, I have a website done in ASP.Net MVC which hosted in Azure and it will try to connect to a VM machine hosted on Azure which has MongodDB installed and running. tt will need to connect to port 27017. 

When I tested on my local machine, I can connect to the VM MondgoDB no issues, then I published to Azure web site and it brought up www.microsoftonline.com login, saying sign in the Azure Active directory on the title bar and prompted login for "sign in with your work or school account.

It seems to me Azure has certain fire wall or ??? to prevent port 27017 from the web server (xxxxx.azurewebsites.net). Any ideas?

Thanks
