I'm curious how Fusion interacts with my OS X firewall, and how exposed the rest of my Mac is in general. I have a Linksys router, and it's set as tight as I can make it, as well as my OS X Filesharing/Firewall/Remote Access settings. (I have no wireless or Bluetooth devices.) Yet, I've set no Firewall settings in my Windows/Fusion/Boot Camp drive at all. So is that a leak that a hacker can exploit and gain access to my Mac drives? Or do my Mac settings apply themselves to the Windows drive?
