 ## <a name="whatis"></a>What is a virtual network gateway?
 
-A virtual network gateway is composed of two or more virtual machines that are deployed to a specific subnet you create, which is called the *gateway subnet*. The VMs that are located in the gateway subnet are created when you create the virtual network gateway. Virtual network gateway VMs are configured to contain routing tables and gateway services specific to the gateway. You can't directly configure the VMs that are part of the virtual network gateway and you should never deploy additional resources to the gateway subnet.

+A virtual network can have two virtual network gateways; one VPN gateway and one ExpressRoute gateway - as is the case with [coexisting](#coexisting) connection configurations. The gateway type 'vpn' specifies that the type of virtual network gateway created is a **VPN gateway**, rather than an ExpressRoute gateway.
 
 VPN gateways can be deployed in Azure Availability Zones. This brings resiliency, scalability, and higher availability to virtual network gateways. Deploying gateways in Azure Availability Zones physically and logically separates gateways within a region, while protecting your on-premises network connectivity to Azure from zone-level failures. see [About zone-redundant virtual network gateways in Azure Availability Zones](about-zone-redundant-vnet-gateways.md)
 
-Creating a virtual network gateway can take up to 45 minutes to complete. When you create a virtual network gateway, gateway VMs are deployed to the gateway subnet and configured with the settings that you specify. One of the settings you configure is the gateway type. The gateway type 'vpn' specifies that the type of virtual network gateway created is a VPN gateway. After you create a VPN gateway, you can create an IPsec/IKE VPN tunnel connection between that VPN gateway and another VPN gateway (VNet-to-VNet), or create a cross-premises IPsec/IKE VPN tunnel connection between the VPN gateway and an on-premises VPN device (Site-to-Site). You can also create a Point-to-Site VPN connection (VPN over OpenVPN, IKEv2 or SSTP), which lets you connect to your virtual network from a remote location, such as from a conference or from home.
