I am trying to connect to my office share drive using the Mac VPN client. The connection works at home, and has worked at several other locations. Where I am having trouble is connecting to the share over my mobile hotspot, or any hotspot for that matter. The VPN connects, but when I go to connect to the share, the connection fails. I have verified that the ip address at the office 10.0.0.xxx is different than the ip address for the hotspot. Any thoughts about why this will not work on the hotspots?
