I am successfully using OSX Lion as my host and running Windows 7 in Parallels. But Windows 7 is my 'work' environment and the Mac is my personal environment. What I'd like to do is run the mac wirelessly through the airport and have parallels/Windows7 use the ethernet port so that they are on different networks. Is this possible? I see where I can configure Parallels to use the ethernet card. But is there a way to force the mac to use wireless even though an ethernet cable is plugged in?
