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)
