I've been trying to straighten this out for a couple days now, but I'm still a bit turned around, so I was hoping to tap this group's collective expertise to help me. I'll try and keep this as simple as possible. What I want to do: Attach a drive to my home (wireless) network so I can back things up. Make this drive available via FTP from anywhere on the internet (with un/pw protection, obviously) so that I can sync folders between work and home, or get files I left at home when I'm on vacation. There are two ways I think I can do this: Option 1: Purchase the new n-enabled flat Airport Extreme and put my current external HD onto the USB port for use with AirPort Disk. The only question I have here is whether I can port-forward the router so I can access the drive from outside my network. Option 2: Buy a small NAS and port-forward it using the ethernet port on my spaceship/boob shaped AX. I'm relatively sure this is possible, but I don't have any way to test personally, as I have not yet bought an NAS. Cost isn't really the issue here (the AX is actually more expensive than the little NAS I'm looking at, but I'll likely end up getting one anyway when I get a new MBP when Leopard comes out), ease of use is. So, the question is: Can I do what I want? Which method is easier? Or is it six of one, half a dozen of the other?
