+NFS Azure file shares are supported in all the same regions that support premium file storage. See [Azure products available by region](https://azure.microsoft.com/explore/global-infrastructure/products-by-region/?products=storage&regions=all).
 
-## Prerequisites
+## Step 1: Create an NFS Azure file share
 
-- [Create an NFS share](storage-files-how-to-create-nfs-shares.md).
-- Open port 2049 on the client you want to mount your NFS share to.
+If you haven't already done so, [create an NFS Azure file share](storage-files-how-to-create-nfs-shares.md).
 
-    > [!IMPORTANT]
-    > NFS shares can only be accessed from trusted networks.
+## Step 2: Configure network security
 
-- Either [create a private endpoint](storage-files-networking-endpoints.md#create-a-private-endpoint) (recommended) or [restrict access to your public endpoint](storage-files-networking-endpoints.md#restrict-public-endpoint-access).
-- To enable hybrid access to an NFS Azure file share, use one of the following networking solutions:
-    - [Configure a Point-to-Site (P2S) VPN on Linux for use with Azure Files](storage-files-configure-p2s-vpn-linux.md).
-    - [Configure a Site-to-Site VPN for use with Azure Files](storage-files-configure-s2s-vpn.md).
-    - Configure [ExpressRoute](../../expressroute/expressroute-introduction.md).
+NFS shares can only be accessed from trusted networks. Currently, the only way to secure the data in your storage account is by using a virtual network and other network security settings. Any other tools used to secure data, including account key authorization, Microsoft Entra security, and access control lists (ACLs) can't be used to authorize an NFSv4.1 request.
 
-## Disable secure transfer
+> [!IMPORTANT]
+> The NFSv4.1 protocol runs on port 2049. If you're connecting from an on-premises network, make sure that your client allows outgoing communication through those ports. If you've granted access to specific VNets, make sure that any network security groups associated with those VNets don't contain security rules that block incoming communication through those ports.
+
+To use NFS Azure file shares, you must either [create a private endpoint](storage-files-networking-endpoints.md#create-a-private-endpoint) (recommended) or [restrict access to your public endpoint](storage-files-networking-endpoints.md#restrict-public-endpoint-access).

+- Configure [ExpressRoute](../../expressroute/expressroute-introduction.md).
+
+Azure Files doesn't currently support encryption-in-transit with the NFS protocol and relies instead on network-level security. Therefore, you'll need to disable secure transfer on your storage account.

+## Step 3: Mount an NFS Azure file share
 
-The following mount options are recommended or required when mounting NFS Azure file shares.
+You can mount the share using the Azure portal. You can also create a record in the **/etc/fstab** file to automatically mount the share every time the Linux server or VM boots.
 
-| **Mount option** | **Recommended value** | **Description** |
-|******************|***********************|*****************|
-| `vers` | 4 | Required. Specifies which version of the NFS protocol to use. Azure Files only supports NFS v4.1. |
-| `minorversion` | 1 | Required. Specifies the minor version of the NFS protocol. Some Linux distros don't recognize minor versions on the `vers` parameter. So instead of `vers=4.1`, use `vers=4,minorversion=1`. |
-| `sec` | sys | Required. Specifies the type of security to use when authenticating an NFS connection. Setting `sec=sys` uses the local UNIX UIDs and GIDs that use AUTH_SYS to authenticate NFS operations. |
-| `rsize` | 1048576 | Recommended. Sets the maximum number of bytes to be transferred in a single NFS read operation. Specifying the maximum level of 1048576 bytes will usually result in the best performance. |
-| `wsize` | 1048576 | Recommended. Sets the maximum number of bytes to be transferred in a single NFS write operation. Specifying the maximum level of 1048576 bytes will usually result in the best performance. |
-| `noresvport` | n/a | Recommended. Tells the NFS client to use a non-privileged source port when communicating with an NFS server for the mount point. Using the `noresvport` mount option helps ensure that your NFS share has uninterrupted availability after a reconnection. Using this option is strongly recommended for achieving high availability. |
-| `actimeo` | 30-60 | Recommended. Specifying `actimeo` sets all of `acregmin`, `acregmax`, `acdirmin`, and `acdirmax` to the same value. Using a value lower than 30 seconds can cause performance degradation because attribute caches for files and directories expire too quickly. We recommend setting `actimeo` between 30 and 60 seconds. |
