FMES P2P ports

I've been using Stratus to develop a p2p webconference app and now that FMS 4/FMES is released with support of RTMFP, I was wondering if FMES dynamically assigned the ports like Stratus?  Like the following:

1) The initial connection to Stratus for a fingerprint ID connected with a port in the range of 10000-10100

2) The p2p connections were established based on the fingerprint ID anywhere between 1024-65535

Is that still how the p2p connections with FMES work, or is there now a way to possibly define the ports?

Another question, assuming the above is still true, if the machines that will be directly connected with p2p are on a local network behind the same firewall, the only UDP ports that would need to be openned/configured would be 10000-10100 to talk to the server. Once the fingerprints are established, the machines should be wide open within their own network to connect to each other, correct?

Thanks in advance!
