I haven't tried using the VPN Client in a Parallels for Mac OSX guest 
VM. Do you have a VPN services running on the host? If so, there is 
probably a racoon process running that may be swallowing NAT-T UDP 
packets on port 4500. You may need to shut this down. I'm not sure how 
sophisticated the Mac OSX IPsec implementation is. After porting the 
Shrew Soft client to OSX not too long ago, it seems like it could have 
some issues with NAT-T. The problem being that you don't set NAT-T 
options on individual socket descriptors, its a system wide setting.

How bout some log output?
