[AG-TECH] Strange behavior with bridge

G'day Paul and Chris

Something that I would investigate is that you don't have any firewalls
running locally on the box.

As can be seen here http://agcentral.org/help/how-to/bridgeserver, I
have been using a similar configuration except that I bridge each room
individually, ie 

      name = CQU 
      location = Rockhampton 
      qbexec = /usr/bin/QuickBridge 
      #use this port range for the bridge server as a whole 
      portMin = 20000 
      portMax = 39999 
      #CQU Lobby 
      type = Venue

Please feel free to contact me directly if you are still having problems
as I am running the bridgeServer on Fedora Core 4 without any issues.

No light, but I can confirm that I could only see my own video when I  
used your bridge a few minutes ago, despite several other streams  
being vislble in multicast mode.

Although I've seen this "BRIDGESERVER = ...." mentioned in some  
recent documentation, I've never used it on the APAG venue server/ 
bridge. Still, I doubt its inclusion would cause your problem.

Is the behaviour any different when you explicitly bridge all/any  
rooms individually, rather than the "whole server" mode? e.g.

# Arctic Circle venue at ARSC test venue server
type = Venue

What version of the toolkit?
