Create inbound SNAT Rule

Is there a way to configure a inbound source NAT rule with some azure service like Azure Load Balancer or similar?

Public IP addr. -> Private IP addr. -> virtual Machine.
So that the packets arriving at the Virtual Maschine do have the private IP address as the source IP address instead of the public IP address.

Thanks!

    Hi,

    Azure Application Gateway is correct for your needs based on your description. The incoming requests would be received on the Application Gateway's public listener and then a new TCP connection would be created to the VM and the original request would be sent. The source IP would be the gateway's private IP address.
