Hi!
I've missed this post in the feeds, anyway…

Why did you need an internet connection for the Time Capsule? A friend of mine uses the backup solution offered by that using a private network, different from the cabled connection with public IP that his main Mac has.

So, I was wondering, Kiran could be connected via wi-fi over the campus broadband connection, and locally to her TC via a private network using an ethernet adapter. What I am missing in the scenario?
