Can someone please educate me on exactly how I can access my Time Capsule from any other network aside from my own (over the Internet?)

I don't have a static IP address, so would I need DNS forwarding? Would it involve checking my home network's IP while away? Should I get static IP?

Many thanks!!

Let's start with; what are you trying to do? –  Harv Jan 19 '11 at 1:14

If You Have a Time Capsule or an AirPort Extreme Base Station with Shared USB Hard Drive

If you have either a Time Capsule (which is basically an AirPort Extreme Base Station with a built-in 500 GB or 1 TB hard drive) or an AirPort Extreme Base Station (AEBS) with an attached USB hard drive, you can share out the Time Capsule/AEBS hard drive and make it accessible via the Internet. To do this:

  1. Start the Airport Utility.

  2. Select your Time Capsule or AEBS. Make a note of the IP Address shown on the right -- you will need it later.

  3. Click Manual Setup.

  4. Check your "Connection Sharing" setting under the Internet Tab. The following tutorial is valid if your "Connection Sharing" is to "Share a public IP address", the normal setup for a home network. You will need to have a static IP address, or use a free dynamic DNS service. If you have a different type of "Connection Sharing," you probably don't need a tutorial to set up remote access to your disk; adapt this one as needed.

  5. Click Disks (at the top of the dialog box), and then click File Sharing.

  6. Select (check) the "Enable file sharing" checkbox and the "Share disks over Ethernet WAN port" checkbox. It is strongly recommended that you also set Secure Shared Disks to "With base station password" and Guest Access to "Not allowed"; not making these changes may allow unauthorized users to access your Time Capsule/AEBS hard drive.

  7. Click Airport (at the top of the dialog box), and then click Base Station.

  8. Enter a Base Station Password and verify it in the Verify Password box.
  9. Click Advanced (at the top of the dialog box), and then click Port Mapping.
  10. Click the plus sign (+) to add a new port mapping.

  11. In the Public UDP Port(s) and Public TCP Port(s) boxes, type in a 4-digit port number (e.g., 5678) that you choose. In the Private IP Address box, type the internal IP address of your Time Capsule or AEBS that you wrote down in step 2 (for example, 192.168.0.1). In the Private UDP Port(s) and Private TCP Port(s) boxes, type 548. Click Continue.

  12. In the Description box, type a descriptive name like "Time Capsule File Sharing" or "AEBS File Sharing". Then, click Done.

  13. When you have made all changes, click Update.

Your Time Capsule/AEBS will restart. Once it does, you are now ready to connect to the Time Capsule/AEBS hard drive via the Internet. To do this when your MBA is away from home:

  1. In the Finder, click Go > Connect to Server.
  2. Type in the correct domain name or external IP address for your network, plus a colon and the port number you specified in step 11. For example, "www.myhomedomain.com:5678" or "123.123.12.123:5678".

  3. Click Connect.

  4. You will be prompted for your user name and password. The user name can be anything you like; the password should be the password for the Time Capsule/AEBS which you specified above.

  5. Click Connect.

Voilà! You are now connected to your Time Capsule/AEBS hard drive from your MBA. You can access files, copy files back and forth between your MBA and the hard drive, delete files, whatever you want, as long as your MBA remains network-connected. The next time you go to connect, it should go even more quickly (especially if you save your password in your keychain, and if you add your home IP address/domain name to your list of Favorite Servers in the Connect dialog box).

Note that the Time Capsule/AEBS will appear in the Shared section of your Finder's sidebar as a server, with the Base Station Name of the Time Capsule/AEBS as the server name.

Cool, have seen this guide... was hoping for a 'non-DNS forwarding version', but guess not. –  AlexW Jan 19 '11 at 15:33
    
That works. However, this transaction is all in plain/text and not encrypted correct? –  user6137 Apr 30 '11 at 5:22
    
Get a static IP to help the process along nicely... –  AlexW Jul 21 '11 at 3:43

If you know your IP-number you do not need a DNS-name –  Thorbjørn Ravn Andersen Jul 24 '11 at 20:50

you can use services like dyndns.org to map a static domain name to a dynamic ip address. also I think @AlexW you mean port-forwarding and not DNS-forwarding. –  cwd Oct 24 '11 at 18:53

I believe the AEBS port should be 5009 for access via Airport Utility. I set up a test network with a Linksys WRT160N router in the middle, and an AEBS and my MacBook connected to LAN ports of the WRT160N. I ran Airport Utility on the MacBook, then tried "Configure Other" (from the File menu). I got a prompt for the IP address and password of the AEBS. I was able to successfully connect when I entered the IP address 192.168.1.2:5009 or just 192.168.1.2, but the connection failed if I tried 192.168.1.2:548.

Next I connected to a "live" WRT160N over the internet. I configured a port forwarding entry (using "Applications & Gaming") for 5009, to forward to an AEBS behind the WRT160N. Then I ran Airport Utility, did another Configure Other, and BINGO! It worked. When I tried the same process using port 548, it failed.

Maybe 548 is the port to use to access files on a Time Capsule, or a disk attached to an AEBS?

Good job Steve, nice BINGO! moment when it connected no doubt :) –  AlexW Nov 29 '11 at 14:10

You have to set up port forwarding or a NAT on your home internet router mapping the port to the internal ip address of your time capsule.

Can you please be a bit more specific, especially about which ports to map and how to configure the TC? –  patrix Feb 13 '12 at 19:24
    
My understanding was PF/NAT is so you can reach machines behind the router and not the router itself. Can you expand on this a bit? –  bmike Nov 13 '12 at 22:42
