Application Issue - Adobe connect unable to handle "unreachable" responses

Hi,

We've discovered what seems to be a bug with the Adobe Connect application/flash player.

For some reason when you have a proxy in place adobe connect still attempts to establish a direct connection to the adobe servers (for example na7fms2.adobeconnect.com), if these packets get dropped video plays with no issue.

However in our case we have ACL's setup on our Cisco routing core (which do not allow this traffic), which in turn respond with "Destination Unreachable (Communication administratively filtered)".

Adobe Connect seems to be unable to handle these responses and goes into a loop continiously attempting a direct connection (around every 10-12 seconds), therefore causing streaming video's to restart every 10-12 seconds.

Below is a screenshot of the packet capture of the accurance.

Basically we managed to create two of the following scenarios in our network.

Video restarts every 10-12 seconds:

Video plays with no issues:

Now this "Destination Unreachable" response is completely legal in terms of RFC http://www.ietf.org/rfc/rfc792.txt

It would be great if this issue could be raised as a bug and fixed in future versions.

Thanks,

Daniil
