As far as I can tell Parallels does not work thru Little Snitch. I conclude this from the fact that in LS tables Parallels is not given any authorization and yet it has no problems accesssing Internet. 2 questions: 1) How is ths possible since I thought that everything works thru LS? 2) How can I alter this behaviour i.o.w. force Parallels to work thru LS?
I think this is a side effect of the way the ethernet interface is "switched" for parallels. The host OS doesn't see any of the traffic coming from the virtual machine. One workaround would be to install a little snitch-like application on windows, like the excellent free ZoneAlarm. (www.zonelabs.com)
