Q: Ho to configure the "Roaming Network" using the current AirPort Utility

Hi, I have a question about this roaming network. With the current AirPort Utility I do not know how to select "share a public IP" on "connection Sharing" on the first AirPort. Maybe someone can tell me how to configure this. It would be great if Apple would update this...

 

Maybe this is important: I use a Time Capsule as my first base station. The second one is a AirPort Extreme and the third one an Airport Express.

 

If I just set the first device to "Bridge Mode" I loose the internet connection with my cabel modem. I get the message "No Internet Conection". If I hook up my mac to the cable modem via ethernet the internet ist still functioning.

 

The funny thing is that I can use the internet for a couple of minutes until it does not work anymore. Everytime I change something the the settings of the Time Capsule (Bridge Mode to DHCT & NAT) I can use the internet for a couple of minutes...??

 

Thank you!

    The Time Capsule connected to your cable modem should be configured to "Share a public IP address" for "Connection Sharing". All the rest should have "connection sharing" set to "Off (Bridge Mode)".

     

    This article explains everything: http://support.apple.com/kb/HT4260

     

    Disconnect your cable modem from power whenever you change what it connected to it.

    Exactly that is my problem. I use the AirPort Utility 6.0 and I can not find "Share a public IP address". I can only find "Router Mode" and then I can select from: a) "DHCP and NAT" b) "DHCP Only" and c) "Bridge Mode".

     

    I hope I have the terms correctly since I use the AirPort Utility in German and I am not sure my translation is OK. Maybe someone can post a screen shot?

    Download and install AirPort Utility for Lion: AirPort Utility 5.6.

     

    If you examine the article I provided (http://support.apple.com/kb/HT4260) it should appear identical to what you will see in AirPort Utility 5.6.

     

    AirPort Utility 6.0 lacks many features. I do not use it so I cannot determine where you might find the applicable settings. Use AirPort Utility 5.6.

    Using AirPort Utility 5.6:

     

    Connection Sharing: "Share a public IP address":

    I can only find "Router Mode" and then I can select from: a) "DHCP and NAT" b) "DHCP Only" and c) "Bridge Mode".

    DHCP and NAT would be the same setting as Share a public IP address.

     

    Recommend that you use AirPort Utility 5.6 as John suggests. It will track with the instructions that you have.

    Thank you, allmost there...

     

    Thanks John and Bob. I did as you suggested and I am online again :-)

     

    Unfortunately I still have one problem. My settings are as proposed by John:

     

    1) Cabel Modem (Fritz!Box 6360 Cable)

    connected to

    2) Primary AirPort = Time Capsul connected via ethernet - configured as "Share a public IP address"

    3) Second AirPort = AirPort Extreme connected via ethernet - configured as "Bridge"

    4) Third AirPort = AirPort Express connected via ethernet - configured as "Bridge"

     

    It works fine. I can walk through the house and have internet everywhere. The only problem is that the Time Capsule is blinking yellow and tells me: Status Double-NAT. Do you know what could happen? Is it OK to ignore or can I cure this?

    I just found the solution to the "Double-Nat Status". It sure took me a while but since this "error" does not do any harm I just ignored it for a while.

     

    Right now I changed the setup presented by Apple to set up a roaming network.

    Inseat of using one of my airports as the primary station I conected the Fritz!Box cable modem to a switch. From this switch I go via ethernet to all airports in the house. All Airports are used in "Bridge Mode" and everthing is working great without errors.

    If everything is working properly, your Fritzbox cable modem must actually be a combination modem / router.

     

    That would explain it. You should have only one router. A switch connected directly to a modem with no router would only be capable of serving one client.
