-A virtual network gateway is composed of two or more Azure-managed VMs that are automatically configured and deployed to a specific subnet that you create called the **gateway subnet**. The gateway VMs contain routing tables and run specific gateway services. When you create a virtual network gateway, the gateway VMs are automatically deployed to the gateway subnet (always named *GatwaySubnet*), and configured with the settings that you specified.
