I am running a PPTP server on an E2500 running Shibby's V123. Great build - PPTP sets up easily and my Surface 2 RT connects without issue. Whatismyip.com shows my router's IP address and location. However, www.dnsleaktest.com shows DNS servers from my location's ISP (hotel wifi) rather than those from my router's ISP. There aren't a ton of configuration settings in the GUI and I don't see much on the Windows end either. Also - not a ton of information on the net either.
I sure wish that the Surface 2 RT would support OpenVPN and end my issues, but until that day…. Can anyone else shed some light on DNS with a PPTP VPN?
