How do I access my AE attached lacie drive from the web

Question

I just hooked up a 1TB drive to my new AE and think I have it configured properly in the disk pane of airport utility. I'm very much hoping that I have it configured correctly! I chose to configure "with a disk password", and not " accounts", and just for the heck of it clicked on the "?" [airport utility help] at the bottom of the Disks/File Sharing page. At the bottom of the page in help under "sharing a usb hard disk on your network", under " to set up disk sharing:" #4 "select the " share disks over ethernet WAN port" checkbox if you want to provide remote access to the disk over the wan port", It turns out that I don't have that message on my airport utility pane for Disk/ file sharing. I do have a checkbox that says " share disks over the internet using Bonjour, but I definitely don't have a checkbox that says " ethernet wan port" as a choice.
Why would my pane be missing that choice? I recall setting up the AE choosing to be able to use computers with the pre 802.11n compatability. Should I have chosen the 5ghz which is 802.11n only as I recall.
I hope this all isn't sounding to complicated. I just want to be able to access my hard drive [connected to the AE] remotely from the web and hopefully be able to access a huge music library that i have on that drive. HELP, PLEASE, KIND APPLE PEOPLE!

Answer 1

It is attached to another router.
In order to access a drive from the Internet, you need to know the Public IP address of the router and the router would need to be configured to port map the file service requests from the Internet to the drive. Apple provides Leopard and Snow Leopard users a means to access drives attached to an 802.11n AirPort Extreme Base Station (AEBSn), from the Internet, by using a feature known as "Back to My Mac." You may want to explore this option further.
Without Back to My Mac, the router would need to be manually configured to make this work. In a much simpler case where the 802.11 AirPort Extreme Base Station (AEBSn) is directly connected to the Internet modem, you would use the AirPort Utility to determine its Public IP address and to configure it for port mapping. The only difficult issue is the type of Public IP address that your ISP provides you. Most consumer-grade Internet service comes with a dynamic IP address. That means this address will change periodically and you will need to keep track of the changes in order to be successful in accessing it from the Internet. One way to do this is to use a DDNS service, like DynDNS.
In your case, there is an added level of complexity since the AEBSn is downstream of another router. You would have to configure both this router and the AEBSn to get this to work.
Should I try to set up with accounts, would that be different in regards to this problem?
The 802.11n AirPort Extreme Base Station (AEBSn) can share out a hard drive with three types of access: 1) Base Station Password, 2) Disk Password, or 3) With Accounts. Which type you choose will not affect the drive from being accessed from the Internet.
