360 Wireless Bridging/streaming Problem....help Options

[violinjjb]

My Current Setup
Main Router Belkin Pre-N 192.168.1.1 (Connected to XP Home Desktop 192.168.1.2 wired)
Client Bridge Router (buffalo dd-wrt) with LAN IP as 192.168.1.9
Xbox 360 ip as 192.168.1.3 connected through Wireless Bridge.

My entire network is setup on the same subnet 192.168.1.x
I also have a laptop (XP pro) behind the bridge, that is 192.168.1.4

I run wpa in network, with no problems.

I can connect to XBOX live no problems. I can also connect my laptop to the internet through the bridge.
I can even ping my laptop through from my desktop computer. I know it is not possible to ping the 360.

I have Downloaded both WMP11 and the Zune Software onto my desktop.

I have forwarded the ports that MS recommends to open in both routers (router and bridge).

I have taken down all firewalls.

I have all routers allowing UPnP. Loopback is disabled.

When I run either media sharing program, it doesn't see the 360. Also, the 360 doesn't see the computer running the programs. Is there anything I am forgetting. Is there anything I should try? My router sees the Xbox, but my computer doesn't. HELP PLEASE. I want to be able to stream media to the 360. Thanks in advance!
