FMS troubles

I'm trying to troubleshoot an app that is using FMS. It works fine for me, but my client is behind a pretty secure firewall. I had them do the port test and here is there results:

RTMP DEFAULT Success
RTMP 80 Failed
RTMP 443 Failed
RTMP 1935 Failed
HTTP Tunneling DEFAULT Success
HTTP Tunneling 80 Success

I know they can see other FMS content, but cannot see mine.

I did the same port test and received the following results:

RTMP DEFAULT TimeOut
RTMP 80 Failed
RTMP 443 Success
RTMP 1935 Failed
HTTP Tunneling DEFAULT Success
HTTP Tunneling 80 Success

I then created a similar test connecting to our FMS and got the following results:

RMTP Default: Success 0.3s
RMTP Port 1935: Rejected 0.3s
RMTP Port 80: Closed 0s
RMTP Port 80: Closed 0s
RMTPT (Tunneling) Default: Timed Out 20.1s
RMTPT (Tunneling) Default: Closed 20.1s
RMTPT (Tunneling) Port 443: Timed Out 20.1s
RMTPT (Tunneling) Port 443: Closed 20.1s

I'm thinkg is has something to do with how the FMS is configured, but know nothing about it. Can someone help me figure this out, or give me advice to give to my server guy to get this up and running correctly????

Thanks in advance.
