openvpn and vmware fusion - can os x and VM share a tun/tap device?

tunnelblick 3.0b6
virtual machine is xp pro sp2

in mac os x tunnelblick is able to successfully create the vpn tunnel across the tun/tap device. when i execute ifconfig in terminal i see the tap device listed. when i look at system preferences -> network i don't see the virtual device listed. this is my first mac so i am not sure if that is expected behavior. just for the sake of comparison, the virtual device was listed in my "network connections" on my previous xp pro machine.

the vmware fusion windows xp VM however, only has access to the airport network connection. it would be nice if the xp vm could piggyback off of the os x tun/tap device. is this possible? at this point i am just going to install openvpn in the vm as well - nothing like having multiple vpn connections from the same hardware 😉

i have read that tunnelblick has some issues on 10.5, but i have only noticed odd behavior when my laptop goes to sleep.

thanks for any help!

macbook, Mac OS X (10.5.2)

So I'm a recent convert to Mac from Vista, and have the same config you do...

Use tunnelblick to establish the VPN, and configure your VM to Share the network connection (NAT). This will then allow your XP client to route traffic through the VPN tunnel.

I've also noticed issues w/ Tunnelblick VPN's when my MacBook goes to sleep (usually when I close the lid to go to a meeting). I'm sure there is some Mac Expert that has a "preferred" method to resolving this, but I found that going into Activity Monitor and forcing a quit on the "openvpn" process fixes the issue. This is basically resetting the tap0 adapater.

Hope this helps.
