Need help quick. E3000 no longer work as a bridge device after I flash dd-wrt

[xellos2099alpha]

Long story short, I am currently using Att U-verse and I used to connect linksys E3000 to use it as bridge device and as a wireless and it work fine. However, I have a need to upgrade the router to dd-wrt. I upgrade successful, howeverm, somehow I can't get the E3000 as a bridge again, even with the same setting. Here is my old setting on how to get it to work. Any advice is appreciated.

What's providing DHCP?
Generally you don't want to use the WAN/Internet port or have DHCP enabled on a router that you want to only act as a bridge/WAP/switch etc.
But your screen shot shows an IP address of 192.168.1.253 for the WAN/Internet port, and a default gateway of 192.168.1.254. What is 192.168.1.254? Your primary router I presume?

Then you have the router itself handing out 192.168.2.0/24 addresses.
This means you still have it configured as a router, as it needs to route between the 2 networks.
Based on that screen shot, it's still configured just like a router would be that's getting double-NAT'ed.

Also a good question to ask would be, what are you trying to accomplish and what exactly "doesn't work?"
