Stratus tunneling over ports 443 and/or 80

Question

Would it be possible to have Stratus listen on ports 443 and
80; and would Flash Player 10 indeed fall back to those ports, as
with FMS?
I am dealing with a customer who has difficulty opening 1935
due to corporate policies.
I have no information about port 10000+. Hopefully they pose
no problem.
Kind Regards,
Frans

Answer 1

The older RTMP operates over TCP port 1935 and falls back to
tunneling over 443 and/or 80.
The newer RTMFP uses UDP and requires the ability to make
outbound connections to 1935 and also higher port numbers in order
to establish a server connection.
Running over port 443 and 80 UDP wouldn't help, the firewall
is likely configured to open up TCP 443 (HTTPS) and TCP 80 (HTTP)
while still blocking UDP.
If your application needs to work in the presence of
UDP-blocking firewalls (and note that we do several things to get
through them, if they do allow internally-initiated UDP sessions),
you'll need to code your own fallback to a TCP protocol like RTMP
or HTTP.
