I have a WL-500gP v2 with ASUS official 2.0.1.2 and 2.0.1.3 beta firmware which support the "cool" Media Server feature. I was able to access the media files on the WL-500gP v2 from my Nokia N810 and stream audio and video. But once I connected to my ADSL from the WL-500gP v2, my N810 can no longer find the Media Server. Neither was I able to connect to the samba shares through hostname ("WL-500g.Premium2" by default). If I disconnected from my ADSL the above two things worked again. I tried different UPnP devices but they all have the same problem.

Does anyone have any idea on how this could happen?
