I set up a VPN connecting via SSTP & EAP-MSCHAP-V2. This works on multiple machines, just not on this one running Windows 8.

It doesn't matter if I connect via 3G or via WiFi - whenever I connect the VPN, all network connections go to "Limited". I don't have any connection to any outside world (not the VPN I'm connecting to, nor the Internet). I tried looking through the route table, but can't find anything odd. I just don't know where to start looking (the IP the VPN assigns me also seems OK).

The Routing table looks like this when being connected:
Code:

Tracert just times out. Ping times out. What else can I try? Sidenote: OpenVPN works fine.
