Configure a site-to-site VPN for use with Azure Files

Article
09/30/2024

You can use a site-to-site (S2S) VPN connection to mount your Azure file shares from your on-premises network, without sending data over the open internet. You can set up a S2S VPN using Azure VPN Gateway, which is an Azure resource offering VPN services. You deploy VPN Gateway in a resource group alongside storage accounts or other Azure resources.

We strongly recommend that you read Azure Files networking overview before continuing with this article for a complete discussion of the networking options available for Azure Files.

The article details the steps to configure a site-to-site VPN to mount Azure file shares directly on-premises. If you're looking to route sync traffic for Azure File Sync over a S2S VPN, see configuring Azure File Sync proxy and firewall settings.

Prerequisites

An Azure file share you would like to mount on-premises. Azure file shares are deployed within storage accounts, which are management constructs that represent a shared pool of storage in which you can deploy multiple file shares, as well as other storage resources, such as blobs or queues. You can learn more about how to deploy Azure file shares and storage accounts in Create an Azure file share.
A network appliance or server in your on-premises data center that's compatible with Azure VPN Gateway. Azure Files is agnostic of the on-premises network appliance chosen, but Azure VPN Gateway maintains a list of tested devices. Different network appliances offer different features, performance characteristics, and management functionalities, so consider these when selecting a network appliance.

If you don't have an existing network appliance, Windows Server contains a built-in Server Role, Routing and Remote Access (RRAS), which can be used as the on-premises network appliance. To learn more about how to configure Routing and Remote Access in Windows Server, see RAS Gateway.

Add virtual network to storage account

To add a new or existing virtual network to your storage account, follow these steps.

Sign in to the Azure portal and navigate to the storage account containing the Azure file share you would like to mount on-premises.
In the service menu, under Security + networking, select Networking. Unless you added a virtual network to your storage account when you created it, the resulting pane should have the radio button for Enabled from all networks selected under Public network access.
To add a virtual network, select the Enabled from selected virtual networks and IP addresses radio button. Under the Virtual networks subheading, select either + Add existing virtual network or + Add new virtual network. Creating a new virtual network will result in a new Azure resource being created. The new or existing virtual network resource must be in the same region as the storage account, but it doesn't need to be in the same resource group or subscription. However, keep in mind that the resource group, region, and subscription you deploy your virtual network into must match where you deploy your virtual network gateway in the next step.

If you add an existing virtual network, you must first create a gateway subnet on the virtual network. You'll be asked to select one or more subnets of that virtual network. If you create a new virtual network, you'll create a subnet as part of the creation process. You can add more subnets later through the resulting Azure resource for the virtual network.

If you haven't enabled public network access to the virtual network previously, the Microsoft.Storage service endpoint will need to be added to the virtual network subnet. This can take up to 15 minutes to complete, although in most cases it will complete much faster. Until this operation has completed, you won't be able to access the Azure file shares within that storage account, including via the VPN connection.

If you want to add a new virtual network and gateway subnet, run the following script. If you have an existing virtual network that you want to use, then skip this step and proceed to step 3. Be sure to replace <your-subscription-id>, <resource-group>, and <storage-account-name> with your own values. If desired, provide your own values for $location and $vnetName. The -AddressPrefix parameter defines the IP address blocks for the virtual network and the subnet, so replace those with your respective values.

# Select subscription  
$subscriptionId = "<your-subscription-id>"
Select-AzSubscription -SubscriptionId $subscriptionId

# Define parameters
$storageAccount = "<storage-account-name>"
$resourceGroup = "<resource-group>"
$location = "China East 2" # Change to desired Azure region
$vnetName = "myVNet"
# Virtual network gateway can only be created in subnet with name 'GatewaySubnet'.
$subnetName = "GatewaySubnet"
$vnetAddressPrefix = "10.0.0.0/16" # Update this address as per your requirements
$subnetAddressPrefix = "10.0.0.0/24" # Update this address as per your requirements

# Set current storage account
Set-AzCurrentStorageAccount -ResourceGroupName $resourceGroup -Name $storageAccount

# Define subnet configuration  
$subnetConfig = New-AzVirtualNetworkSubnetConfig -Name $subnetName -AddressPrefix $subnetAddressPrefix

# Create a virtual network  
New-AzVirtualNetwork -Name $vnetName -ResourceGroupName $resourceGroup -Location $location -AddressPrefix $vnetAddressPrefix -Subnet $subnetConfig

If you created a new virtual network and subnet in the previous step, then skip this step. If you have an existing virtual network you want to use, you must first create a gateway subnet on the virtual network before you can deploy a virtual network gateway.

To add a gateway subnet to an existing virtual network, run the following script. Be sure to replace <your-subscription-id>, <resource-group>, and <virtual-network-name> with your own values. The $subnetAddressPrefix parameter defines the IP address block for the subnet, so replace the IP address per your requirements.

# Select subscription  
$subscriptionId = "<your-subscription-id>"
Select-AzSubscription -SubscriptionId $subscriptionId

# Define parameters
$storageAccount = "<storage-account-name>"
$resourceGroup = "<resource-group>"
$vnetName = "<virtual-network-name>"
# Virtual network gateway can only be created in subnet with name 'GatewaySubnet'.
$subnetName = "GatewaySubnet"
$subnetAddressPrefix = "10.0.0.0/24" # Update this address as per your requirements

# Set current storage account
Set-AzCurrentStorageAccount -ResourceGroupName $resourceGroup -Name $storageAccount

# Get the virtual network
$vnet = Get-AzVirtualNetwork -Name $vnetName -ResourceGroupName $resourceGroup

# Add the gateway subnet
Add-AzVirtualNetworkSubnetConfig -Name $subnetName -VirtualNetwork $vnet -AddressPrefix $subnetAddressPrefix

# Apply the configuration to the virtual network
Set-AzVirtualNetwork -VirtualNetwork $vnet

To allow traffic only from specific virtual networks, use the Update-AzStorageAccountNetworkRuleSet command and set the -DefaultAction parameter to Deny.
```
Update-AzStorageAccountNetworkRuleSet -ResourceGroupName $resourceGroup -Name $storageAccount -DefaultAction Deny
```
Enable a Microsoft.Storage service endpoint on the virtual network and subnet. This can take up to 15 minutes to complete, although in most cases it will complete much faster. Until this operation has completed, you won't be able to access the Azure file shares within that storage account, including via the VPN connection. The service endpoint routes traffic from the virtual network through an optimal path to the Azure Storage service. The identities of the subnet and the virtual network are also transmitted with each request.
```
Get-AzVirtualNetwork -ResourceGroupName $resourceGroup -Name $vnetName | Set-AzVirtualNetworkSubnetConfig -Name $subnetName -AddressPrefix $subnetAddressPrefix -ServiceEndpoint "Microsoft.Storage.Global" | Set-AzVirtualNetwork
```

Add a network rule for the virtual network and subnet.

$subnet = Get-AzVirtualNetwork -ResourceGroupName $resourceGroup -Name $vnetName | Get-AzVirtualNetworkSubnetConfig -Name $subnetName
Add-AzStorageAccountNetworkRule -ResourceGroupName $resourceGroup -Name $storageAccount -VirtualNetworkResourceId $subnet.Id

If you want to add a new virtual network and gateway subnet, run the following script. If you have an existing virtual network that you want to use, then skip this step and proceed to step 3. Be sure to replace <your-subscription-id>, <storage-account-name>, and <resource-group> with your own values. Replace <virtual-network-name> with the name of the new virtual network you want to create. The --address-prefix and --subnet-prefixes parameters define the IP address blocks for the virtual network and the subnet, so replace those with your respective values. The virtual network will be created in the same region as the resource group.

# Set your subscription  
az account set --subscription "<your-subscription-id>"  

# Define parameters
storageAccount="<storage-account-name>"
resourceGroup="<resource-group>"
vnetName="<virtual-network-name>"
# Virtual network gateway can only be created in subnet with name 'GatewaySubnet'.
subnetName="GatewaySubnet"
vnetAddressPrefix="10.0.0.0/16" # Update this address per your requirements
subnetAddressPrefix="10.0.0.0/24" # Update this address per your requirements

# Create a virtual network and subnet
az network vnet create \
  --resource-group $resourceGroup \
  --name $vnetName \
  --address-prefix $vnetAddressPrefix \
  --subnet-name $subnetName \
  --subnet-prefixes $subnetAddressPrefix

To add a gateway subnet to an existing virtual network, run the following script. Be sure to replace <your-subscription-id>, <resource-group>, and <virtual-network-name> with your own values. The --address-prefixes parameter defines the IP address block for the subnet, so replace the IP address block as needed.

# Set your subscription  
az account set --subscription "<your-subscription-id>"

# Define parameters
storageAccount="<storage-account-name>"
resourceGroup="<resource-group>"
vnetName="<virtual-network-name>"
# Virtual network gateway can only be created in subnet with name 'GatewaySubnet'.
subnetName="GatewaySubnet"
subnetAddressPrefix="10.0.0.0/24" # Update this address per your requirements

# Create the gateway subnet
az network vnet subnet create \
  --resource-group $resourceGroup \
  --vnet-name $vnetName \
  --name $subnetName \
  --address-prefixes $subnetAddressPrefix

To allow traffic only from specific virtual networks, use the az storage account update command and set the --default-action parameter to Deny.
```
az storage account update --resource-group $resourceGroup --name $storageAccount --default-action Deny
```
Enable a Microsoft.Storage service endpoint on the virtual network and subnet. This can take up to 15 minutes to complete, although in most cases it will complete much faster. Until this operation has completed, you won't be able to access the Azure file shares within that storage account, including via the VPN connection.
```
az network vnet subnet update --resource-group $resourceGroup --vnet-name $vnetName --name $subnetName --service-endpoints "Microsoft.Storage.Global"
```

Add a network rule for the virtual network and subnet.

subnetid=$(az network vnet subnet show --resource-group $resourceGroup --vnet-name $vnetName --name $subnetName --query id --output tsv)
az storage account network-rule add --resource-group $resourceGroup --account-name $storageAccount --subnet $subnetid

Deploy a virtual network gateway

To deploy a virtual network gateway, follow these steps.

In the search box at the top of the Azure portal, search for and then select Virtual network gateways. The Virtual network gateways page should appear. At the top of the page, select + Create.
On the Basics tab, fill in the values for Project details and Instance details. Your virtual network gateway must be in the same subscription, Azure region, and resource group as the virtual network.
- Subscription: Select the subscription you want to use from the dropdown.
- Resource Group: This setting is autofilled when you select your virtual network on this page.
- Name: Name your virtual network gateway. Naming your gateway isn't the same as naming a gateway subnet. It's the name of the virtual network gateway object you're creating.
- Region: Select the region in which you want to create this resource. The region for the virtual network gateway must be the same as the virtual network.
- Gateway type: Select VPN. VPN gateways use the virtual network gateway type VPN.
- SKU: Select the gateway SKU that supports the features you want to use from the dropdown. The SKU controls the number of allowed Site-to-Site tunnels and desired performance of the VPN. See Gateway SKUs. Don't use the Basic SKU if you want to use IKEv2 authentication (route-based VPN).
- Generation: Select the generation you want to use. We recommend using a Generation2 SKU. For more information, see Gateway SKUs.
- Virtual network: From the dropdown, select the virtual network you added to your storage account in the previous step.
- Subnet: This field should be grayed out and list the name of the gateway subnet you created, along with its IP address range. If you instead see a Gateway subnet address range field with a text box, then you haven't yet configured a gateway subnet on the virtual network.
Specify the values for the Public IP address that gets associated to the virtual network gateway. The public IP address is assigned to this object when the virtual network gateway is created. The only time the primary public IP address changes is when the gateway is deleted and re-created. It doesn't change across resizing, resetting, or other internal maintenance/upgrades.
- Public IP address: The IP address of the virtual network gateway that will be exposed to the internet. Likely, you'll need to create a new IP address, however you may also use an existing unused IP address. If you select Create new, a new IP address Azure resource will be created in the same resource group as the virtual network gateway, and the Public IP address name will be the name of the newly created IP address. If you select Use existing, you must select the existing unused IP address.
- Public IP address name: In the text box, type a name for your public IP address instance.
- Public IP address SKU: Setting is autoselected.
- Assignment: The assignment is typically autoselected and can be either Dynamic or Static.
- Enable active-active mode: Select Disabled. Only enable this setting if you're creating an active-active gateway configuration. To learn more about active-active mode, see Highly available cross-premises and VNet-to-VNet connectivity.
- Configure BGP: Select Disabled, unless your configuration specifically requires Border Gateway Protocol. If you do require this setting, the default ASN is 65515, although this value can be changed. To learn more about this setting, see About BGP with Azure VPN Gateway.
Select Review + create to run validation. Once validation passes, select Create to deploy the virtual network gateway. Deployment can take up to 45 minutes to complete.

First, request a public IP address. If you have an existing unused IP address that you want to use, you can skip this step. Replace <resource-group> with your resource group name, and specify the same Azure region that you used for your virtual network.
```
$gwpip = New-AzPublicIpAddress -Name "mypublicip" -ResourceGroupName "<resource-group>" -Location "China East 2" -AllocationMethod Static -Sku Standard
```

Next, create the gateway IP address configuration by defining the subnet and the public IP address to use. The public IP address of the VPN gateway will be exposed to the internet. Replace <virtual-network-name> and <resource-group> with your own values.

$vnet = Get-AzVirtualNetwork -Name <virtual-network-name> -ResourceGroupName <resource-group>
$subnet = Get-AzVirtualNetworkSubnetConfig -Name "GatewaySubnet" -VirtualNetwork $vnet
$gwipconfig = New-AzVirtualNetworkGatewayIpConfig -Name gwipconfig -SubnetId $subnet.Id -PublicIpAddressId $gwpip.Id

Run the following script to create the VPN gateway.

Replace <resource-group> with the same resource group as your virtual network. Specify the gateway SKU that supports the features you want to use. The gateway SKU controls the number of allowed Site-to-Site tunnels and desired performance of the VPN. We recommend using a Generation 2 SKU. Don't use the Basic SKU if you want to use IKEv2 authentication (route-based VPN).
```
New-AzVirtualNetworkGateway -Name MyVnetGateway -ResourceGroupName <resource-group> -Location "China East 2" -IpConfigurations $gwipconfig -GatewayType "Vpn" -VpnType RouteBased -GatewaySku VpnGw2 -VpnGatewayGeneration Generation2
```
You can also choose to include other features like Border Gateway Protocol (BGP) and Active-Active. See the documentation for the New-AzVirtualNetworkGateway cmdlet. If you do require BGP, the default ASN is 65515, although this value can be changed.
Creating a gateway can take 45 minutes or more, depending on the gateway SKU you specified. You can view the VPN gateway using the Get-AzVirtualNetworkGateway cmdlet.
```
Get-AzVirtualNetworkGateway -Name MyVnetGateway -ResourceGroup <resource-group>
```

First, request a public IP address. If you have an existing unused IP address that you want to use, you can skip this step. Replace <resource-group> with your resource group name.
```
az network public-ip create -n mypublicip -g <resource-group>
```
Run the following script to create the VPN gateway. Creating a gateway can take 45 minutes or more, depending on the gateway SKU you specify.

Replace <resource-group> with the same resource group as your virtual network. Specify the gateway SKU that supports the features you want to use. The gateway SKU controls the number of allowed Site-to-Site tunnels and desired performance of the VPN. We recommend using a Generation 2 SKU. Don't use the Basic SKU if you want to use IKEv2 authentication (route-based VPN).
```
az network vnet-gateway create -n MyVnetGateway -l chinaeast2 --public-ip-address mypublicip -g <resource-group> --vnet <virtual-network-name> --gateway-type Vpn --sku VpnGw2 --vpn-gateway-generation Generation2 --no-wait
```
The --no-wait parameter allows the gateway to be created in the background. It doesn't mean that the VPN gateway is created immediately.
You can view the VPN gateway using the following command. If the VPN gateway isn't fully deployed, you'll receive an error message.
```
az network vnet-gateway show -n MyVnetGateway -g <resource-group>
```

Create a local network gateway for your on-premises gateway

A local network gateway is an Azure resource that represents your on-premises network appliance. It's deployed alongside your storage account, virtual network, and virtual network gateway, but doesn't need to be in the same resource group or subscription as the storage account. To create a local network gateway, follow these steps.

In the search box at the top of the Azure portal, search for and select local network gateways. The Local network gateways page should appear. At the top of the page, select + Create.
On the Basics tab, fill in the values for Project details and Instance details.
- Subscription: The desired Azure subscription. This doesn't need to match the subscription used for the virtual network gateway or the storage account.
- Resource group: The desired resource group. This doesn't need to match the resource group used for the virtual network gateway or the storage account.
- Region: The Azure region the local network gateway resource should be created in. This should match the region you selected for the virtual network gateway and the storage account.
- Name: The name of the Azure resource for the local network gateway. This name may be any name you find useful for your management.
- Endpoint: Leave IP address selected.
- IP address: The public IP address of your local gateway on-premises.
- Address space: The address range or ranges for the network this local network gateway represents. For example: 192.168.0.0/16. If you add multiple address space ranges, make sure that the ranges you specify don't overlap with ranges of other networks that you want to connect to. If you plan to use this local network gateway in a BGP-enabled connection, then the minimum prefix you need to declare is the host address of your BGP Peer IP address on your VPN device.
If your organization requires BGP, select the Advanced tab to configure BGP settings. To learn more, see About BGP with Azure VPN Gateway.
Select Review + create to run validation. Once validation passes, select Create to create the local network gateway.

Run the following command to create a new local network gateway. Replace <resource-group> with your own value.

The -AddressPrefix parameter specifies the address range or ranges for the network this local network gateway represents. If you add multiple address space ranges, make sure that the ranges you specify don't overlap with ranges of other networks that you want to connect to.

New-AzLocalNetworkGateway -Name MyLocalGateway -Location "China East 2" -AddressPrefix @('10.101.0.0/24','10.101.1.0/24') -GatewayIpAddress "5.4.3.2" -ResourceGroupName <resource-group>

Run the following command to create a new local network gateway. Replace <resource-group> with your own value.

The --local-address-prefixes parameter specifies the address range or ranges for the network this local network gateway represents. If you add multiple address space ranges, make sure that the ranges you specify don't overlap with ranges of other networks that you want to connect to.

az network local-gateway create --gateway-ip-address 5.4.3.2 --name MyLocalGateway -g <resource-group> --local-address-prefixes 10.101.0.0/24 10.101.1.0/24

Configure on-premises network appliance

The specific steps to configure your on-premises network appliance depend on the network appliance your organization has selected.

When configuring your network appliance, you'll need the following items:

A shared key. This is the same shared key that you specify when creating your site-to-site VPN connection. In our examples, we use a basic shared key such as 'abc123'. We recommend that you generate a more complex key to use that complies with your organization's security requirements.
The public IP address of your virtual network gateway. To find the public IP address of your virtual network gateway using PowerShell, run the following command. In this example, mypublicip is the name of the public IP address resource that you created in an earlier step.
```
Get-AzPublicIpAddress -Name mypublicip -ResourceGroupName <resource-group>
```

Depending on the VPN device that you have, you might be able to download a VPN device configuration script. For more information, see Download VPN device configuration scripts.

The following links provide more configuration information:

For information about compatible VPN devices, see About VPN devices.
Before you configure your VPN device, check for any known device compatibility issues.
For links to device configuration settings, see Validated VPN devices. We provide the device configuration links on a best-effort basis, but it's always best to check with your device manufacturer for the latest configuration information.

The list shows the versions that we tested. If the OS version for your VPN device isn't on the list, it still might be compatible. Check with your device manufacturer.

For IPsec/IKE policy configuration steps, see Configure custom IPsec/IKE connection policies for S2S VPN and VNet-to-VNet.
To connect multiple policy-based VPN devices, see Connect a VPN gateway to multiple on-premises policy-based VPN devices.

Create the site-to-site connection

To complete the deployment of a S2S VPN, you must create a connection between your on-premises network appliance (represented by the local network gateway resource) and the Azure virtual network gateway. To do this, follow these steps.

Navigate to the virtual network gateway you created. In the table of contents for the virtual network gateway, select Settings > Connections, and then select + Add.
On the Basics tab, fill in the values for Project details and Instance details.
- Subscription: The desired Azure subscription.
- Resource group: The desired resource group.
- Connection type: Because this a S2S connection, select Site-to-site (IPSec) from the drop-down list.
- Name: The name of the connection. A virtual network gateway can host multiple connections, so choose a name that's helpful for your management and that will distinguish this particular connection.
- Region: The region you selected for the virtual network gateway and the storage account.
On the Settings tab, supply the following information.
- Virtual network gateway: Select the virtual network gateway you created.
- Local network gateway: Select the local network gateway you created.
- Shared key (PSK): A mixture of letters and numbers used to establish encryption for the connection. The same shared key must be used in both the virtual network and local network gateways. If your gateway device doesn't provide one, you can make one up here and provide it to your device.
- IKE protocol: Depending on your VPN device, select IKEv1 for policy-based VPN or IKEv2 for route-based VPN. To learn more about the two types of VPN gateways, see About policy-based and route-based VPN gateways.
- Use Azure Private IP Address: Checking this option allows you to use Azure private IPs to establish an IPsec VPN connection. Support for private IPs must be set on the VPN gateway for this option to work. It's only supported on AZ Gateway SKUs.
- Enable BGP: Leave unchecked unless your organization specifically requires this setting.
- Enable Custom BGP Addresses: Leave unchecked unless your organization specifically requires this setting.
- FastPath: FastPath is designed to improve the datapath performance between your on-premises network and your virtual network. Learn more.
- IPsec / IKE policy: The IPsec / IKE policy that will be negotiated for the connection. Leave Default selected unless your organization requires a custom policy. Learn more.
- Use policy based traffic selector: Leave disabled unless you need to configure the Azure VPN gateway to connect to a policy-based VPN firewall on premises. If you enable this field, you must ensure your VPN device has the matching traffic selectors defined with all combinations of your on-premises network (local network gateway) prefixes to/from the Azure virtual network prefixes, instead of any-to-any. For example, if your on-premises network prefixes are 10.1.0.0/16 and 10.2.0.0/16, and your virtual network prefixes are 192.168.0.0/16 and 172.16.0.0/16, you would need to specify the following traffic selectors:
  - 10.1.0.0/16 <====> 192.168.0.0/16
  - 10.1.0.0/16 <====> 172.16.0.0/16
  - 10.2.0.0/16 <====> 192.168.0.0/16
  - 10.2.0.0/16 <====> 172.16.0.0/16
- DPD timeout in seconds: Dead Peer Detection Timeout of the connection in seconds. The recommended and default value for this property is 45 seconds.
- Connection mode: Connection mode is used to decide which gateway can initiate the connection. When this value is set to:
  - Default: Both Azure and the on-premises VPN gateway can initiate the connection.
  - ResponderOnly: Azure VPN gateway will never initiate the connection. The on-premises VPN gateway must initiate the connection.
  - InitiatorOnly: Azure VPN gateway will initiate the connection and reject any connection attempts from the on-premises VPN gateway.
Select Review + create to run validation. Once validation passes, select Create to create the connection. You can verify the connection has been made successfully through the virtual network gateway's Connections page.

Run the following commands to create the site-to-site VPN connection between your virtual network gateway and your on-premises device. Be sure to replace the values with your own. The shared key must match the value you used for your VPN device configuration. The -ConnectionType for site-to-site VPN is IPsec.

For more options, see the documentation for the New-AzVirtualNetworkGatewayConnection cmdlet.

Set the variables.

$gateway1 = Get-AzVirtualNetworkGateway -Name MyVnetGateway -ResourceGroupName <resource-group>
$local = Get-AzLocalNetworkGateway -Name MyLocalGateway -ResourceGroupName <resource-group>

Create the VPN connection.

New-AzVirtualNetworkGatewayConnection -Name VNet1toSite1 -ResourceGroupName <resource-group> `
-Location 'China East 2' -VirtualNetworkGateway1 $gateway1 -LocalNetworkGateway2 $local `
-ConnectionType IPsec -SharedKey 'abc123'

After a short while, the connection will be established. You can verify your VPN connection by running the following command. If prompted, select 'A' in order to run 'All'.
```
Get-AzVirtualNetworkGatewayConnection -Name VNet1toSite1 -ResourceGroupName <resource-group>
```
The connection status should show as "Connected."

For more options, see the documentation for the az network vnet create command.

az network vpn-connection create --name VNet1toSite1 --resource-group <resource-group> --vnet-gateway1 MyVnetGateway -l eastus --shared-key abc123 --local-gateway MyLocalGateway

After a short while, the connection will be established. You can verify your VPN connection by running the following command. When the connection is in the process of being established, its connection status shows 'Connecting'. Once the connection is established, the status changes to 'Connected'.

az network vpn-connection show --name VNet1toSite1 --resource-group <resource-group>

The final step in configuring a S2S VPN is verifying that it works for Azure Files. You can do this by mounting your Azure file share on-premises. See the instructions to mount by OS here:
