SMB fileshare - looks like it is timing out on the MS side

Question

I'm trying to mount a fileshare with my mac, and am getting a timeout. Here's the traceroute:

sudo traceroute -p 445 XXXX.file.core.windows.net

traceroute to file.blz21prdstr06a.store.core.windows.net (20.150.90.40), 64 hops max, 52 byte packets

Looks like it is hanging up at MS?

@Scott Fergusson To test port 445 TCP with traceroute please make sure to add the -T flag. Also make sure that if you have a firewall enabled it is allowing the client IP. See Cause 2: Virtual network or firewall rules are enabled on the storage account. Port 445 is not blocked on the Azure side and should be open. However if it is blocked from the ISP you may need to use one of the available workarounds such as deploying File Sync, VPN, or the REST API.

Hope this helps. If you have additional questions or issues please let me know.
