WNR3500L as bridge for DGN2200

Hi everybody.

I really don't know how to get working my brand new Netgear WNR3500L as bridge repeater for my dsl router DGN2200.

I flashed "DD-WRT Kong Mod USB/FTP/miniDLNA/Samba3" succesfully on my WNR3500, then I tried to set it up as bridge repeater, but it won't to connect to internet.

The DGN2200 wireless is set up in this way: 

Its wireless connection works with no problems. I want to extend its signal using the WNR3500, and to do so I read this guide: http://www.dd-wrt.com/wiki/index.php/Repeater_Bridge#Instructions<br 

But it won't work in anyway. I always have to set a manual IP to let the iMac to communicate with the WNR3500, but I have no internet access. 

Please, I really wish someone can help me, I don't know how to get it work :(

Really thanks in advance.
