    I have an AT&T Motorola 2210 modem hooked to my airport extreme the problem is I receive An error that say's double nat. The dsl modem is setup as a PPP so I tell the airport extreme to be dhcp/nat setup. If I put the airport in bridged mode I can connect but only one computer because of ip conflict. So how should I set this up?

    One way to handle this would be to put the modem into bridge mode and let the airport handle the connection. Go into your modems config and goto the PPP location setting under "advanced"
    Change the setting to bridged mode. By selecting this mode you will not be able to do any configuration on the modem without reseting it and wiping the settings. Not a big deal. Your airport will handle the connection now and will handle any port forwarding you need. Read about putting your modem into bridge mode for more information.
