Re: Back to My Mac with Bluewin VDSL?
Hello I had this same issue for 18 months, now I have sat down to fix it.
I have a Centro Piccolo, and I am not sure I have VDSL, but still this might be helpful.
I have been able to obtain some success, which means I have browsed my USB external drive attached to my TimeCapsule connecting to it by the cellular connection of my iPhone (although I was sitting at home next to the TimeCapsule)
The key setting, I believe, is to activate IP Passthrough in the Swisscom modem/router and select the TimeCapsule as the "computer" in the network which will receive all the traffic.
I will test it better tomorrow from work, but the test from cellular should be unmistakable.
