As I’ve reported previously, Back to My Mac hasn’t worked out well for me. Because it shares ports with Windows Home Server (both vie for HTTPS), I haven’t been able to use BTMM.

Now, that’s not really a big deal for me. I have LogMeIn on every system, and that does the job nicely (if not better, when on a non-Mac system). But, I was surprised while in the Intel press room, to find my PowerBook G4 (sitting at home) as available.

At first I thought my AirPort Extreme had dumped its port forwarding table. So, I called up my Windows Home Server. Sure enough, it responded and loaded properly. This means that Apple has updated the NAT translation on the MobileMe servers. It is not a software update on the local machines, but rather a “cloud” fix that has enabled BTMM to work properly.

And, it’s a great fix indeed. It’s actually the same fix that I suggested awhile ago. The MobileMe server checks to see if the standard HTTPS port is routing to something else. In my case it is. So, BTMM is using an alternate port on-the-fly.

With MobileMe actually starting to work properly… I may actually keep my membership after the trial.
