Client Mode Bridge?

I see some people seem to have this working but I simply cannot get it to work. I have the WL-HDD set up to act as a client for my wireless network (no WDS support on the main router/AP) and I would like to connect my PC to the WL-HDD with an ethernet cable and have access to the wireless network. That is I essentially want the WL-HDD to act as an WLAN -> LAN bridge.

I have set it up as I think it should be, and the WL-HDD is connected to the wireless and I can ping the WL-HDD IP successfully from the WLAN. However, no traffic is being passed from the LAN port to the WLAN port. Is there something I have missed?
