If you have an existing Azure Bastion host, you’ll need to ensure it’s using the Standard SKU Tier (not Basic) and there is a new checkbox to tick to allow Native client support (preview).

Windows Firewall settings of the Azure VM operating system allowing RDP But as a best practice, you can add the Subnet IP address range of your Azure Bastion host in this rule, to allow only Bastion to be able to open this port on your VM. Since we’re blocking RDP at the network layer from outside of Azure and the VM only has a private IP address, only RDP connections initiated from inside Azure will be able to take advantage of this. This is standard for connection via Azure Bastion anyway. You will however need to have RDP allowed in Windows Firewall in the VM’s operating system. You also do not need to have RDP allowed in the Azure Network Security Group.Īzure Network Security Group (NSG) inbound port rules Your virtual machine in Microsoft Azure will not require a public IP address. The architecture of a native RDP client connection to an Azure VM via Azure Bastion.

Let’s learn how to configure it and how to use it! With this configuration, we’ll tell the native RDP client to “tunnel through” Azure Bastion, using an Azure CLI command. Introducing (in preview) Connecting to a VM using the native client. What if we could somehow combine the two scenarios?

But wait – the native RDP client software on your Windows PC (known as MSTSC) does support clipboard access, but it’s expecting that the VM will be answering connection requests via an open RDP port. That means you can’t copy local files and paste them into your session to upload them to your VM, or vice versa. The downside to this is the browser-based remote session isn’t capable of accessing your local computer’s clipboard. Then, the Azure Bastion host inside the same Azure virtual network connects to the VM’s RDP port. Instead, the connection to your VM can be made through an Azure Bastion host via your web browser, so your local machine is only connecting on the standard HTTPS port 443. Microsoft recommends you isolate these kinds of management ports from the Internet, in our Best practices for defending Azure Virtual Machines. The RDP protocol is a common target for hacking attempts, including attempts to hijack disconnected RDP sessions and brute-force attacks that repeatedly try to connect with incorrect user credentials. This is especially useful for VMs that are part of an application architecture but provide services or data to other parts of the solution that are already inside Azure (or on-premises via a VPN connection), and the VM doesn’t need to be publicly accessible – but you still need to manage it. Now you can keep port 3389 closed in your Azure Network Security Group and even configure the VM without a public IP address. Microsoft released Azure Bastion as a way to connect with a remote session into a virtual machine (VM) on Microsoft Azure, without needing to have the VM’s RDP port available on the internet.
