FTPS: Implicit SSL/TLS client side port number

Trying to connect to the server using FTPS: Implicit SSL/TLS.
I have two clients, on two different machines, one out in the open, other behind a firewall.
As one might suspect, the one behind the firewall does not connect properly. I get error "Could not retrieve directory listing".
I know that the server requires port 9922, so I made that request to IT (on the client side) and they opened it (apparently).
Is there another port, client specific, on the client side that I need to request?
Everything that I read about passive FTP, it sounds like the client will assign a port of incoming connection, but I'm not sure which one.
I'm trying to avoid going to IT asking for unknown port to be open or some "general type request" as they will not appreciate it (I would not either).


Thanks to all
