@Cataster By Setting up a VPN to your specific Storage Account, the traffic will go through a secure tunnel as opposed to over the internet. Follow the instructions to setup VPN to access Azure Files from Windows.
There is a You video which talks about How to mount Azure File Share using P2S VPN.
Troubleshoot Azure Files problems in Windows (SMB)
Additional information: After configuring the private endpoint of the Storage Account to utilize the correct VNET and subnet that was correlated to the Express Route, and editing the hostfile of the local machine, mounting had become successful. There also required a DNS Zone to be added, and once added, there were no further issues with mounting the file share.
How to configure Point to site connections
Confirm the end-goal was to establish mounting a file share by utilizing an existing Express Route.
Created a private endpoint with the same region as the V-Net and subnets that were required (Ex, Central US).
Once private endpoint was created, edited the host file of the on-prem device to include the private IP of the new endpoint.
Established a mount through File Explorer, utilizing the private IP address from the new endpoint.
The next steps were that you were going to see DNS configurations to ensure that new users could easily route to the Private IP of the new endpoint, and let myself know of your progression from there, and if the case is needed to be closed or if we need to proceed with further assistance.
If you still find any difficulties, please let me know I would like to work closer on the issue. Can you share the complete screenshot of the error message.
Please let us know if you have any further queries. I’m happy to assist you further.
