       - question: How can I see SNAT port usage on NAT gateway?

           There's no SNAT port usage metric for NAT gateway. Use the SNAT Connection Count and Total SNAT Connection Count metrics to help you evaluate the SNATing capacity of your NAT gateway.

       - question: If multiple public IP addresses are assigned to a NAT gateway, is traffic flow disrupted when one of the IP addresses is removed?
         answer: |
           Any active connections associated with a public IP address terminate upon the public IP address being removed. If the NAT gateway resource has multiple public IPs, new traffic is distributed among the assigned IPs.

+      - question: What does it mean when I see an IP being used to connect outbound that is different from my NAT gateway public IP?
+        answer: |
+          There are a few possible reasons for why you could be seeing a different IP being used to connect outbound than the one associated to your NAT gateway. To help troubleshoot, refer to the [NAT Gateway connectivity troubleshooting guide](/azure/nat-gateway/troubleshoot-nat-connectivity#nat-gateway-public-ip-isnt-used-to-connect-outbound).

            Yes. The addition of a NAT gateway to a subnet with service endpoints doesn't affect the endpoints. [Virtual Network service endpoints](../virtual-network/virtual-network-service-endpoints-overview.md) enable a more specific route for the destination Azure service traffic they represent. Traffic for the service endpoint traverses the Azure backbone instead of the internet. Private Link is recommended over service endpoints when connecting to Azure PaaS services directly from your Azure network.
 
+      - question: Can I use NAT gateway with my Databricks workspace?
+        answer: |
+          Yes. NAT gateway can be used in one of two ways with Databricks if you enable secure cluster connectivity in your workspace. If you use secure cluster connectivity with the **default VNet** that Azure Databricks creates, Azure Databricks automatically creates a NAT gateway for outbound traffic from your workspace's subnets. The NAT gateway is created within the managed resource group managed by Azure Databricks. You can't modify this resource group or any resources provisioned within it. If you enable secure cluster connectivity on your workspace that uses VNet injection, you can deploy a NAT gateway on both of the workspace's subnets to provide outbound connectivity. You can modify the configuration for customized outbound connectivity requirements in this case. For more information, see [Secure cluster connectivity](/azure/databricks/security/network/classic/secure-cluster-connectivity).
