PirateBox OpenWrt and MR3020

Hi there,

I'm trying to install OpenWRT on a TL-MR3220 router. I got no problem with the firmware installation, but when I try to ping Google, but I get the following message : ping: bad address 'www.google.com'

I tried two tutorials : David Darts and the one from Pabell.
The firmware I use is OpenWrt for the MR3020 (modified by Matthias Strubel)
My OS is Windows 7.

My Home router IP address is 192.168.2.1
My computer IP address is 192.168.2.11

My network configuration on the OpenWrt router is :

config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'

config interface 'lan'
option ifname 'eth0'
option type 'bridge'
option proto 'static'
option ipaddr '192.168.2.27'
option netmask '255.255.255.0'
option gateway '192.168.2.1'
list dns '192.168.2.1'
list dns '8.8.8.8'

I also edit the firewall configuration and turn the Wifi features.

Thanks for any help you can provide
