I am trying to get Back to My Mac working on my AirPort Extreme. I am at college and I have the router plugged directly into an ethernet port in my room that supplies the internet. On the Internet tab in the AirPort Utility, I have bridge mode selected. When I do this, it tells me (In the Back to My Mac Tab) that I need to have NAT-PMP enabled in my router. So I change it to "Share a public IP" and then it tells me that I have multiple devices connected that have NAT enabled. It appears to me that NAT is supplied by the wall but MobileMe is not recognizing it. Any ideas on how to get this to work? Thanks!
