* **Ensure port 445 is open**: SMB communicates over TCP port 445. On your client machine (the Mac), check to make sure your firewall isn't blocking TCP port 445. If your organization or ISP is blocking port 445, you might need to set up a VPN from on-premises to your Azure storage account with Azure Files exposed on your internal network using private endpoints. With this configuration, traffic will go through a secure tunnel as opposed to over the internet. For more information, see [Networking considerations for direct Azure file share access](storage-files-networking-overview.md). To see a summary of ISPs that allow or disallow access from port 445, go to [TechNet](https://social.technet.microsoft.com/wiki/contents/articles/32346.azure-summary-of-isps-that-allow-disallow-access-from-port-445.aspx).
