I am using Ubuntu 10.04 to access a Windows VPN. I connect to the VPN from Ubuntu, and when I open a Windows 7 virtual machine (VirtualBox), everything works great ... I can access local network drives, ping local servers, remote into local machines, etc.

However, I can do none of this from Ubuntu. With the VPN connected, I cannot even ping anything within the VPN local network. I'm guessing it's a DNS issue that Windows is handling automatically but Ubuntu needs a setting somewhere to tell it to use the DNS servers of the VPN network?

Any ideas? I'm a relative novice to Ubuntu, esp. VPN in Ubuntu.

[EDIT] Actually, I'm almost positive it is DNS, because if I get the IP address from the Windows VM I can use Terminal Server Client to remote into a machine.
