'Back to My Mac' doesn't work over iPhone tethered Internet?

[big_malk]

I used my iPhone as a modem yesterday, and Back to My Mac didn't work, it said my modem didn't support support NAT or uPNP or something along those lines. Is this the case? It shouldn't work?
Just I had a similar issue sometimes with my friends router, it was very temperamental and worked on and off.

In my case, my carrier offers two different APNs for Internet access. The default, "internet", uses a shared IP address that would potentially cause the sort of problems that you're having. There's another one, "direct", that gives me a private IP address.

If your issue is the same sort of thing, then it's going to be a carrier-dependent fix. APN details should be available somewhere on your carrier's support website.

Hmm that could be a problem if that's the case. I'm using the less than official method to get tethering, so I can't expect any help from them when I'm not actually paying for the service

Ah. So it's not just AT&T that's adding a surcharge?
