I really would appreciate some help. I have a 5th Gen Airport Extreme that I am connecting to a Belkin modem/router, and I am really struggling with the settings I need to put into the Extreme. I want to have the Extreme do the work of controlling the NAT's, but I don't know what I need to disable in my modem, and then the correct settings in the Extreme. When I have set DHCP and NAT mode, I get the double NAT error, which I've read so many opinions about. What do I need to disable in the modem to stop this happening? I have run the Extreme in Bridge mode without a problem, but it seems such a waste of its technology to have it work just in bridge mode. Even if someone could point me at a very detailed set up procedure because the Apple manual gives you next to nothing, and even online I'm struggling to find what I need.
