+- A [gateway subnet](../../vpn-gateway/vpn-gateway-about-vpn-gateway-settings.md#gwsub) must be created on the virtual network, and you'll need to know the name of the gateway subnet.
 
 ## Collect environment information
 In order to set up the point-to-site VPN, we first need to collect some information about your environment for use throughout the guide. See the [prerequisites](#prerequisites) section if you have not already created a storage account, virtual network, gateway subnet, and/or private endpoints.

 ## Configure the VPN client
-The Azure virtual network gateway will create a downloadable package with configuration files required to initialize the VPN connection on your on-premises Windows machine. We will configure the VPN connection using the [Always On VPN](/windows-server/remote/remote-access/vpn/always-on-vpn/) feature of Windows 10/Windows Server 2016+. This package also contains executable packages which will configure the legacy Windows VPN client, if so desired. This guide uses Always On VPN rather than the legacy Windows VPN client as the Always On VPN client allows end-users to connect/disconnect from the Azure VPN without having administrator permissions to their machine.

 The following script will install the client certificate required for authentication against the virtual network gateway, download, and install the VPN package. Remember to replace `<computer1>` and `<computer2>` with the desired computers. You can run this script on as many machines as you desire by adding more PowerShell sessions to the `$sessions` array. Your use account must be an administrator on each of these machines. If one of these machines is the local machine you are running the script from, you must run the script from an elevated PowerShell session.
