AT&T Residential Gateway is stating "Router Behind Router" and wants to automatically configure a DMZ, where it assigns the same ip to Firewalla as the Gateway. How should this be handled?

  Which mode are you setting up Firewalla to?  Either way, I would ignore that, and go with Simple mode.

  The problem is that when you try to pull up a webpage it does not allow you and instead that "router behind router" comes up.

  It was working fine, without the router problem.
