Let me give as much info as possible:
macbook pro. Fusion loaded with all patches/updates. Windows 7 OS for Vm. That a machine is a member of the domain (2003 Microsoft). If I pass through the IP address from the wireless device from the Mac, the vm world is fine(except unbearably slow on the LAN.). The nat address will be given properly, and on the same subnet as the host. Great! Communication occurs. great! If the thunderbolt adaptor is the device being forwarded, then the vm will get an IP address from the dhcp server properly. (Verified. For if I put a reservation for the vm MAC address, the vm politely accepts it). Now is where the issue begins. When the wired card is passed through, as soon as the IP address is picked up, no further LAN communications take place. No ping, no print, no access network shares, etc. of course the vm adapter is the standard gigabit (I believe intel) controller. Of course the same adapter is used with the wireless passthrough too, as to the vm it doesn't care. If I allow "double-nat" to occur, then it will work to some extent, but the machine is not on the same subnet. Note that all windows firewalling is turned off. In all likelyhood this appears to be a vm/host bug. The vm machine Cannot ping the host when the wired adapter is passed through, but it can when the wireless is passed through. When double natted, host and child machine can ping just fine on wired adapter passthrough.
IF I take thIs vm and run it from another vm fusion Mac host, it will run fine. So it seems vm host/MacBook pro related.
Anyone seen before, and if so, how to resolve?
