Lately there seem to be some issues with multicast and bridging via NCSA's network. The problem you're describing with unicast does seem about right from what i've seen and may not be a problem with your site at all.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>What you might consider is doing that test again on another venue server with a bridge where multicast is working to your test site(s). LSU's lobby if off the NCSA World venue/lobby and has a bridge, but i can not guarantee that multicast is working to all sites. We AG with many sites (several overseas) where multicast works - our neighbors along the south have no trouble with us either, but this week I know that there are one or two sites that could not see us in the north east.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>I'm running a beaconhere: hostname--> venues.lbrn.lsu.edu).

Our network is not multicast enabled, so we have been trying to make the AG Connector work for weeks now and just about to give up. The documentation of the connector is very sub-optimal, to put it politely. In AG connector -driven multicast, if we manage to keep the connection to the server, which is dropped often, the other parties, who HAVE multicast enabled on their networks can not see or hear us at all (we can hear and see them). In unicast, without the connector, everything works both ways, but we can not see any of the parties (no incoming video), although we can hear them. I know that certain UDP ports must be open, but it must be more complicated than that, since *rarely* the whole system seems to be working well.
