You have an Azure subscription that contains the following resources:
- A virtual network that has a subnet named Subnet1
- Two network security groups (NSGs) named NSG-VM1 and NSG-Subnet1
- A virtual machine named VM1 that has the required Windows Server configurations to allow Remote Desktop connections
NSG-Subnet1 has the default inbound security rules only.
NSG-VM1 has the default inbound security rules and the following custom inbound security rule:
- Priority: 100
- Source: Any
- Source port range: *
- Destination: *
- Destination port range: 3389
- Protocol: UDP
- Action: Allow
VM1 has a public IP address and is connected to Subnet1. NSG-VM1 is associated to the network interface of VM1. NSG-Subnet1 is associated to Subnet1.
You need to be able to establish Remote Desktop connections from the internet to VM1.
Solution: You add an inbound security rule to NSG-Subnet1 that allows connections from the Any source to the *destination for port range 3389 and uses the TCP protocol. You remove NSG-VM1 from the network interface of VM1.
Does this meet the goal?



The default port for RDP is TCP port 3389. A rule to permit RDP traffic must be created automatically when you create your VM.
Note on NSG-Subnet1: Azure routes network traffic between all subnets in a virtual network, by default.
