Help needed with wifi bridge setup (no replies)

Folks,

I am trying to setup dockstar as wifi bridge. I am running stock wheezy with 3.2.0-4-kirkwood kernel.

Main_Router ------> [WiFi link] <-----Dockstar-----Linksys switch----multiple PCs

My /etc/network/interfaces is given below:

auto lo ra0
iface lo inet loopback
iface eth0 inet manual

allow-hotplug ra0
iface ra0 inet manual
pre-up wpa_supplicant -Dwext -i ra0 -c /etc/wpa.conf -B


auto br0
iface br0 inet dhcp
      bridge_ports ra0 eth0
      bridge_stp off
      bridge_maxwait 5
wpa-bridge br0

With this I am not seeing DHCP from dockstar or any PC connected to the switch. I do see wifi link established between router and dockstar.

Can anyone help?

TIA
D Banks
