If you've just installed the AG toolkit and made no configuration  
changes, then the vic that runs is in receive only mode (using AG's  
VideoConsumerService). That means it hasn't transmitted anything to  
open up the firewall (as it did when you transmitted from the command  
line instance). If you reconfigure your VenueClient to run a  
VideoService rather than a VideoConsumerService, then packets will be  
transmitted (thereby opening the firewall and allowing incoming video
