Hey- I'm having some issues with Back to my Mac and the issue seems to be somewhere in the router I have (Airport extreme n-tech Gigabit) but I can't seem to figure it out. I keep getting this error message in the "back to my mac" tab in System Preferences, under MobileMe, that states that NAT-PMP is not supported by the router and that I need to contact the manufacturer to see if there's a way to turn it on. Since the router is Apple's and it's supposed to "just work", I can't seem to find the reason for this error message (Something that the people on the MobileMe support chat agree on, at least) I've tried changing the settings between the DSL modem and the airport so that the NAT-PMP is done on the router instead of the modem, but there was no difference; the error still showed up. Tried also restoring factory settings but no difference. Any other ideas out there? Thanks!
