[AG-TECH] Outside AV not working

[Donald Roeber]

We're running the latest AccessGrid Toolkit on MacOS X, as both a 
VenueServer and a UniCast Bridge for that VenueServer.  The server is 
multicast enabled, and so are clients on the upenn.edu network.  
Clients on the upenn.edu network can connect to the VenueServer and use 
RAT and VIC just fine.  Unfortunately, for people outside of the Penn 
network, audio and video doesn't work, but they can still use the text 
chat built into the VenueClient.  We don't have any firewalls or 
anything like that in place.  Because of a bug in the MacOS X version 
of the AGToolKit we're using manual multicast addressing for each 
venue.  Each venue is assigned a unique IP address for audio and video, 
and a unique even numbered port number for each service as well.

Any help would be greatly appreciated.
