I am running FileZilla FTP Server with passive mode enabled, and due to firewall constraints I have to limit the passive mode port range to only 6 ports.

My question is how would FileZilla handle any situation where more than 6 concurrent FTP connections are active and want to passively upload a file. Would it queue the connections and prioritise them in a first in, first out manner? I'm not too familiar with FTP so any insight would be appreciated.
