    Hi Forum

    I am pulling my hair out over this issue.
    I have recently set up a home network that looks like this:

    Cable modem --> D-Link Router --> Airport Extreme wireless --> laptops

    I can't get back to my mac or torrenting to work at all. I suspect it has something to do with port forwarding witht the two routers, but I can't seem to figure out how to make them work together.

    The D-Link Router has open ports 443, 4500, 5353, and 5354 for btmm and 8500-8600 for torrenting. They are forwarded to the Airport. I have also set it for UPnP.

    The Airport Extreme is set up with BTMM settings, but I cant find a way to open specific ports.

    I can't get any of it to work, so any ideas are appreciated.

    Yup. It sounds like Double NAT. Can you get one of the routers out of the mix? Can you set the Airport to bridge mode?

    To clarify, in your home network, there should be only one box in charge of controlling the various network devices, computers, laptops, etc.

    At the moment it seems your two routers are both saying they're in control, and the laptops are confused as to which one is really in control. (oversimplification).

    To sort this out, tell one of the routers that it's NOT in control, and to just accept and pass on what the other router says. This is called Bridge mode. There might be an option to turn this on, or just go through the menus and turn off DHCP, NAT, Firewall. Make sure firewall is on on the other router.

    If there's no computers connected to the D-link, you could put that in bridge mode, otherwise it's gonna have to be the Airport express.
