As I suspect too, but as yet, I've not figured it out. I can as above download files just fine, so the data channel can be established for that, and I am using Passive Mode, so it *Should* be only my end (the client) that initiates a connection for the data channel. Also, two versions of FileZilla *Appear* to succeed uploading a file, no errors regarding being unable to setup a data channel, just that when you look on the FreeBSD box later, the file is zero bytes in size.
