I have an existing scale set with Application Gateway. I want to add some NAT rules with port forwarding to the scale set instances. So I created a load balancer with inbound NAT rules, and associated it with VMSS. It didn’t throw any error while creation, but now I don’t have any outbound internet connection. Is it possible to create both application gateway and load balancer for a VMSS? If not, is there any other way to create NAT rules?
This was because I had created a standard load balancer which doesn't provide outbound connectivity by default. We are required to add a load balancing rule, or every instance of scale set needs to have its own public ip.
