Ok, so I'm thinking about getting a Airport Extreme, and have a few questions.

1) Are the Ethernet ports 10/100/1000 ?

2) Can I setup MAC based access with WEP or WPA security?

3) Does it support uPnP ?

4) Can I setup IP reservations for my other devices? iPhones, Laptops, Servers, etc..

5) Does it support Port Forwarding?

6) Can I plug in a External Drive and use it as a Time Machine backup device?

I think that is about it for now. If your wondering why I want MAC based access, it's just a habit for me, as I use it on all our Cisco AP's at work.
