For security reasons I would like to back up to a Time Capsule over the internet.

 

BUT my ISP is blocking port 548.

 

I have managed to port forward on the Time Capsule (to port 5678 at the moment), and I can mount the remote discdrive on the computer.

I can even set the disc as the one Time Capsule should use, but when I try to start the backup, Time Machine says the "Back Up drive is not available" (hope the translations is right).

 

I assume that Time Machine tries to connect to the remote TC on port 548 and that is the reason for the trouble?

 

But is there a way to make Time Machine use a different port?

 

(As a sidenote the drive name is "ServerBU1" no spaces, asterixes or other weird characters)

    Using BTMM via iCloud might work.. I have not asked if you can then do a TM backup via that.. but you probably can. You are taking a risk btw as the backup is far more likely to get corrupted over the internet than waiting until you get home.

     

    Anyway you cannot use a different port to the WAN interface. When you setup the TC to access internet access you are allowing AFP access via WAN.

     

    What you will need to do is turn off wan access and then forward port 5678 to the TC IP 10.0.1.1 by default on port 548. It might then work.. if not I would recommend a different approach.. put the TC in bridge and use another router.. then you will be more readily able to pass the port to the TC on LAN side.

     

    An even better method is to use VPN.. get a router that does pptp or ipsec vpn server.. you can then connect to it as a client and the computer at the other end then has full access to all network resources.. these can be fairly cheap.. a router that takes dd-wrt version with openvpn will work fine.. or look at the second hand market for linksys or netgear stuff like RV042..

     

    TM will assume AFP on normal port.. but it might accept the translation without hiccup.. not sure of that one.. as long as you set the disk access it will try.

    I have never had much success with BTMM but I will try that again :-)

    As I write above, this is what I have working at the moment. But TM is unable to use. But the advice will be good for someone else, and you don't need a second router, just portforward to the local address of the TC.

    I hadn't thought about that. Though it means more equipment, it sounds like something that should actually work!

     

    I'll try that out and get back with the results, when I get the new equipment.

    VPN did the trick!

     

    I used an old Mac Mine (used for Minecraft for the kids) to act as a VPN server, and Time Machine is now backing up!

     

    Thank you for the idea.

    Hmm, by error I hit my answer as the corrext answer, and I can't seem to reverse it, but it was LaPastenaguewho came up with it. Sorry to he/she....

    I've been struggling for months, got my MacBook Pro on VPN, but when I go to Time Machine Prefs it doesn't show the TM source as available, even though I can connect to it in Finder.  It is on a Lion Server with Time Machine Services.  Works great at home, but not on the road!  Ugh.

     

    For us newbies, what is BTMM?

    BTMM = Back To My Mac.

    Thanks Ivan. That brings up a "BTW" - how can I make use of BTMM? I've wondered that for a while. Can I remote control a screen using that? Do they all have to be the same iCloud account?

     

    Right now I am using VNC ports through my firewall, or VNC within a VPN tunnel. But it would be nicer if I could do it directly.
