SharePoint 2013 Farm in Windows Azure IAAS

I have followed the below article to build a sharepoint 2013 farm in WA VMs.

Now, I'm able to hit the SharePoint URL from the VM, but not from internet. From internet : "page cannot be displayed". Not sure if the problem is at sharepoint server or windows azure side. Any help would be really appriciated.
