virtual machine scale sets NSG support
Virtual machine scale sets (VMSS) do not have any feature which can allow blocking certain IP addresses from accessing it via load balancer. It would be great to have network security group support for VMSS to allow blocking unwanted traffic from the internet.
Thanks for the feedback!, this feature is already in place, for VMSS you can assign an NSG at the subnet level, this will enable you to control the traffic on your VMSS.

That's is working now?
Is it possible to apply the NSG to VMSS instance level?
