Greetings, I have a following question. We have an open meetings
system installed on one of our university servers. Now, it is placed
inside a local network. Other hosts inside this network can interact
with this system via 5080 port, but for the outside users the
OpenMeetings server is not available (more precisely, the port 5080 is
not available to them). Let's mark this as Server A.

Now, we have a second server B with Moodle 2.0 installed on it. Also,
we added OpenMeetings connector module inside the Moodle system,
pointing to the Server A. The question is, will this system work.
Server B is adressed from the outside using the 80 port via HTTP. What
happens, when the user launches the OpenMeetings module in  order to
join the conference? It is not quite clear from the documentation, and
I have not studied the codes of connector thoroughly. As far as I
understand, there are two scenarios possible.

Scenario A. Server B connects with server A via 5080 port (that's
possible, since they both are inside the local network). The video/
audio stream is sent to the server B, and server B resends everything
to user via 80 port. In that case there is no need to provide the
internet users access to the additional ports for servers A or B,
however, this means, that both servers have the same load with video/
audio streams. Is this the scenario that actually has place?

Scenario B. Server B connects with server A (perfoms authentification
procedure), but it gives user direct connection to server A, and a
window is displayed inside the page containing all the dataflow. In
that case we have to open 5080 port of server A to internet users (but
not server B 5080 port), and also it means, that all the load of video/
audio streams is concentrated on server A, and server B is not too
heavily loaded, it just serves as the tool for establishing the
connection between user and server B.

Which scenario actually is the one? Depending on this we'll have to
use different security policies inside our network. It's an important
issue for us.
