PS3 Nat Type 3 - Airport Extreme Router

I am Having the same exact Problem here and setup I have a Motorla Modem, Airport Extream and a Switch (Linksys).. I have a "double nat" on my airport and when I switch to "bridging mode" like it recommends I get the IP address being used twice so theirfor I can't get on the internet and I have to resort back to using a single IP address over ethernet. So I believe that's the issue.. I've also found some sites that recommend me to open some ports which I did and I set the PS3 on a Ip address so I know it's set for just that PS3 the ports are open but I still have problems.. Anyone have a solution?

Welcome to the discussions!

It sounds like you have PPPoE setup on the modem with the AEBS connecting using ethernet, is that correct?

Please confirm if this is the case as I will give you instructions to eliminate the double NAT by reconfiguring the modem as a bridge and the AEBS will provide the PPPoE service.

Yes sir. That is correct.. I have my PPoE setup on my modem.. I believe I have an understanding on what to do but not the "correct" procedure. My experience would be a Trial and error and I would grealy appericate the Steps I need to take.. Thank you! Bob Timmons

I have the same Motorola model 2210, but the screen shots in the original post were different, so you may have to search a bit for things.

The 2210 provides NAT service, and the only way to hook it up to the AEBS to Connect Using "Ethernet" will result in the double NAT because the AEBS is also furnishing NAT services.

You will need to use the web interface for your modem and you will probably need to plug it into your computer to configure it. The setup page(s) on my model will display when you enter 192.168.1.254 into your browser. Check your documentation to see if you will use the name address or a different address.

When you log into the modem, look for an Advanced setting, PPP Location, or similar. You need to change the PPP setting from the current "On the Modem" to "On the computer or router". If there is a setting for "Bridge Mode", you can use this as well. Update to save changes on your modem and it will restart.

Important...you may not be able to get back into the modem configuration again unless you reset the modem by holding in the reset button for approx 10 seconds. Then you will be able to reconfigure the modem if you need to do so.

Reconnect the modem to the AEBS and open AirPort Utility - Manual Setup. If AirPort Utility does not "see" the AEBS, temporarily connect an ethernet cable from your computer to one of the LAN <-> ports on the AEBS and try again.

After you click Manual Setup, click the Internet icon at the top of the setup pane and look for the Connect Using setting. You need to change this to PPPoE. Then enter your user name (probably your email address with the ISP) and password. Important....leave the Service Name area completely blank. Do not enter anything here.

Click Update and the AEBS should restart with a green light in about 20 seconds. You have now eliminated the double NAT between the modem and AEBS. Sorry, I can't help with details on the game console, so there may be some additional configuration needed for that device.

Please post back on your progress.

Thank you so, so much. I am not the OP but had the exact same issue he had and I was able to fix it due to your solution. It was very easy and did exactly what I was needing it too. I can not thank you enough!

THANK YOU !!! I just hope many other people find this thread because this is most likely and issue with a lot of other people... 5 Stars to this with an A+ Thank you.. this operation worked VERY smoothly, I anticipated an error would occur but didn't. Thank You

Great! Glad this worked for you and the other users.
