create predefined NSG for Azure Datacenters IP Range
Let's say I have a VM that I want to restrict access from the outside. I want this VM to be accessible from my onprem IPs and from Azure IPs (since a part of my infrastructure is on azure). Since at the moment of discussion ARM VMs do not support static IP address, it will be very useful to create a NSG for allowing traffic only from azure IP ranges. Right now you cannot create such NSG because a NSG only allows a maximum of 100 rules. So, it will be a great idea to have predefined NSG to limit traffic from particular datacenters.
Thanks for the feedback, service tag is called AzureCloud and it’s already available in all regions
Perhaps an NSG per Region...auto updates for all the Azure Subnets in that Region.
