I just wanted to share a quick tip on something that had been tripping me up. I’ve happily been running Windows 7 x64 for around a month now. At work, our VPN hardware doesn’t support 64-bit (different topic, don’t ask), so I wanted to use the VPN client from within Windows XP Mode. Sounds good, right?

One problem. The VPN client couldn’t see outside networks. In fact, I couldn’t even ping.

The default networking adapter seems to be “Shared Networking (NAT)” – just change it to your actual network adapter.

Success!
