Connect to Azure Storage Files Service Over P2S VPN Connection RRS feed

  • Question

  • I want to connect to Azure Storage file shares from on-premise Win10 Pro machine. Due to port 445 being blocked by ISP, I'll need to connect via an Azure P2S VPN connection. What is the best practice to route SMB 3.0 traffic from my Win10 machine through the P2S VPN?

    Thanks, Brian

  • Our Azure VPN Gateway doesn’t support NAT or forward proxy functionality, which is needed to be able to use tunneling to bypass port 445 being blocked. It is on the Networking team’s roadmap but no ETA yet.  

    We are instead collaborating with Networking team to publish list of Azure Files specific IP ranges per region, so you can work with your IT/ISP to unblock port 445 outbound access to limited set of IPs. If there is urgency, Azure IP ranges would be a start – it is all Azure IP ranges and inclusive of Azure Files. This list gets updated weekly, so customer will have to keep the rules updated periodically.
