So I recently got an Airport Extreme and hooked it up to my Westell modem (model: C90-610030-06). Innitially I had the router bridging to the modem, but I wanted it the other way around. So I turned the modem on bridge mode and disabled the LAN dhcp (had to do both to get rid of the "double NAT error"). In Airport Utility, I then connected using PPPoE (previously via DHCP but there was an "internet connection" error and switching to PPPoE solved that). And the router is in DHCP and NAT mode. I also added the iMac, that the router is hooked up to via ethernet, to the DHCP reservations.
On the Airport Extreme, the light is green. The Airport Utility shows no errors. However, the light next to where it says "Internet" is orange. At this point, Im confused how to resolve this problem. I've spent so many countless hours resolving the double NAT issue (despite putting the modem on bridge mode) that I am done fiddling around with this.
I realize I might be missing something obvious so ANY help would be appretiated. Ill be glad to give any more relevant info if needed.
Also, I really don't want to go through the hassle of solving my problem any other way than the route I've taken. I realize it might not be the most "efficient" but it's what I need to do.
Thanks for the info.
I gave it my best shot, but failed.
I can only relate that configuring my AirPort to Connect Using = PPPoE with the modem set to Bridge Mode has worked reliably for me for years. The same setup has worked for my neighbor for a number of months since I set it up for him.
I'm using the setup recommended by ATT...nothing new, nothing different, no static IPs, no custom settings, just following the instructions.
If you decide to try the Motorola 2210 or 3360 modem, please post back on your results.
