[Galene] Troubleshooting 0kbps/0kbps video

[Michael Aldridge <aldridge.mac@gmail.com>]

Hello,

I'm trying to deploy Galene as an internal video conferencing system and
I'm running into trouble getting the video to work.  My network topology
is as follows:

Laptop -> VPN Server -> Proxy -> Proxy -> Proxy -> Galene

The proxies are forwarding either HTTP or HTTPs traffic all the way
inwards.  Galene is configured with -insecure and a proxy applies
trusted TLS to its connections.

Loading the main page, selecting a room, and using the text chat works
just fine, what doesn't work is actually setting up a call.  If I log
two workstations as "presenters" then they each see their own video, but
report 0kbps+0kbps.

I suspect that the magic bullet is going to be adding a TURN server
somewhere, but I know not where.  At no point in this topology does NAT
occur, so I had thought I could get away without one.  My best guess is
that I'd need to amend my diagram as follows:

         -> TURN Server
        /
Laptop -> VPN Server -> Proxy -> Proxy -> Proxy -> Galene

I can provide debug logs on request, I just don't really know what I'm
looking for here.  Thanks in advance for any pointers.
