Problem connecting to VPN when using Personal Hotspot on Macbook
Hi everyone - I have a 2011 MacBook Pro, hooked up to an iPhone4 via USB Personal hotspot while I am travelling. Internet connection works fine providing the mobile network is working ok, EXCEPT I cannot connect to VPN on my Server (SBS 2011) at the office.
iPhone on its own can connect to VPN using the VPN function on the phone - so its not a 3G issue. I know this because even when I connect the phone to a wireless broadband connection, and connect the Macbook to the phone using USB personal hotspot, I still can't connect to VPN on the MacBook.
The MacBook connects to VPN just fine if its connected directly to a wireless broadband connection - ie no phone involved.
So it seems to be a problem of the Macbook not being able to connect to VPN when using Personal Hotspot to access the internet.
This I am finding very frustrating - can anyone suggest a solution to this? Could it be a simple setting I need to change?
thanks
MacBook Pro (13-inch Early 2011), Mac OS X (10.7.3)
