Hey all,
So here's the deal:
DGL-4500 fw: 1.15
DAP-1522 fw: 1.02 (I get better wireless transfer rate with the older firmware)
My 1 xbox 360 is upstairs plugged directly into the DGL-4500
The computer I'm hosting Winamp Remote (aka Orb) on is downstairs hooked through the DAP-1522.  I can share files and see other computers on the network just fine.  I can even see the Xbox as well.  
The problem is:  The xbox 360 upstairs cannot see the Orb sharing.   My xbox 360 downstairs plugged into the DAP-1522 can see it just fine.
All of the ip addresses are reserved and filesharing works among the computers, so I have no idea why I can't see the Orb share on the upstairs 360...could it be a firmware issue releating to Upnp?
Thank you,
Fo
