How do I get a Netopia 3000 DSL modem to work in bridge mode?!

I'm going absolutely crazy here! I previously had a 2Wire DSL modem set to bridge mode with the Linksys router handling PPPoE auth. I recently moved and I'm trying to do the same thing with a new Motorola 3347 (Netopia 3000) and I can't get it to work to save my life.

On the modem I set the following:

DHCP Server: Off
Enable System Bridge: On

I then connected the router's WAN port to one of the modem's ethernet ports. The WAN status on the router shows a WAN IP of and a status of "Connecting..." indefinitely.

I also tried unselecting Enable Gateway Option on the modem, which didn't do anything.

I've been at it for hours and I cannot get this to work. I just want the modem to act as a simple modem, passing the public IP to the router and not doing any routing or anything else. Please -PLEASE- help me get this working...

Have you tried turning on DHCP on at the modem? That setting on a modem usually doesn't mean NAT, it just means that it will use DHCP to communicate the public IP address to whatever's plugged into it.

Response by poster: I've tried just about every combination of the above settings I can think of. However, the few places online that address this situation all say to disable DHCP when enabling bridge mode.

You definitely need to disable DHCP to be in bridge mode.

It looks like the web interface may be somewhat finicky. I don't have one of these devices, nor do I know what the user interface looks like, but I'd guess you're not changing the settings in whatever magic sequence is required for them to take effect.

Response by poster: I followed the steps in that blog post when I first started messing with this. No dice...
