Windows XP and Firewall protection with AirPort
I have my Airport set up as a closed network and realize when I am using my Mac OSX that I have full firewall protection. When I initiate Windows XP and turn my firewall settings off by going to Settings > Control Panel > Windows Firewall am I still protected because of how Airport is set up and provides a firewall? BTW I have full Norton Anti Virus for Windows installed on this Mac.
MacBook Pro, Mac OS X (10.5.2)
