Port forwarding

At times, there is a need where a request should always redirect to a virtual machine. Azure load balancer helps us achieve this with the NAT rules. NAT rules are evaluated after load balancing rules are evaluated and none of its rules are satisfied. NAT rules are evaluated for each incoming request and once it finds them, it forwards the request to that virtual machine through a backend pool. It is to be noted that a virtual machine cannot register the same port for both port forwarding using NAT and load balancing rules.
