Virtual PC, Tiger, Cisco VPN


I'm trying to connect to my work's network (Windows) using a Cisco VPN client (for Windows) running on my 1.8 G5 running 10.4. I have already updated Virtual PC to the latest version.

When not using Virtual Switch I can connect to the internet through Virtual PC. I seem to be able to connect to my work network when I run the Cisco VPN (no errors, etc.), but I can't seem to actually DO anything.

I have tried using Virtual Switch, but the Virtual PC won't even connect to the internet then.

I cannot ask the IT guys at work (all PC). I'm hoping someone here can help me out. Thanks in advance.
