Tutorial: Configure both routing preference options for a virtual machine using the Azure portal
This article shows you how to configure both routing preference options (Internet and Microsoft global network) for a virtual machine (VM). This configuration is achieved using two virtual network interfaces. One network interface is configured with a public IP routed via the Microsoft global network. The other network interface is configured with a public IP routed via an ISP network.
In this tutorial, you learn how to:
- Create a virtual machine with a public IP address with the Microsoft network routing preference.
- Create a public IP address with the Internet routing preference.
- Create a secondary network interface for the virtual machine.
- Associate the Internet routing preference public IP to the virtual machine secondary network interface.
- Attach secondary network interface to virtual machine.
Prerequisites
- An Azure account with an active subscription. Create an account for free.

Select myPublicIP-IR.
In the Overview page of myPublic-IR, select Associate.
In Associate public IP address, select Network interface in the Resource type pull-down box.
Select myVMNic2 in the Network interface pull-down box.
Select OK.
Attach secondary network interface to virtual machine
In this section, you'll attach the secondary network interface you created previously to the virtual machine.
In the portal search box, enter Virtual machine. In the search results, select Virtual machines.
Select myVM.
Stop myVM if it's running, otherwise continue to next step.
In myVM, select Networking in Settings.
In Networking of myVM, select Attach network interface.
