In passive mode the FTP Server choose a random port to data connection, right? I would need use this port on Port Fowarding software. But, in this mode, the port is random. I cannot redirect a random port. So, I need use active mode for have a specifical port to redirect.

Did you solve it with FileZilla by restricting the active mode port range to a single port? So you can do the same for the passive mode, but on the server side.
