Proxy Azure Websites

I´m trying to proxy an external site (Azure Web App, not ASE). I have created the node with FQDN to websitexxx.azurewebsites.net with connection over https. The problem is that (I think) is that bigip resolv ip and connect over IP instead of fqdn to the backend resource and not using SNI. Because of that Azure don´t find the correct website. Is it possible to get this working with different serverssl profiles?
