I have the latest AirPort Extreme base station (MC340LL/A) and have a 2TB hard drive connected to it. It's working beautifully, just as Apple advertised. I set up a guest network, so I don't have to give out my private network's password. That also works as advertised. But now for the tricky part. What I don't want is for guest network users to see the AirPort Disk. And yet I see no option in the AirPort Extreme setup software that allows me to disable AirPort Disk access for the guest network. Yes, I can disable access for the guest account on my computer, but not for the guest network. Of course I have set a good, strong password for the disk, but I'd really like for it not to be seen at all, when not connected to my private network. Does anybody have any clues? Any ideas, hints? Alternative places to look?
