Sorry for answering so late, I was away for a few days. Downloading with FileZilla is working fine I'm using the latest free jar, 2.1.0 free.
The log for a transfer ist always like:

after the last Byte is transferred, it's needing excatly 3 minutes for recieving the 226 Transfer complete Message.
A Filezilla Log looks like:

no timecode here, but i'm only waiting about 5-10 secs after the data was transferred.
For both transfers i'm using a tunnel to the remote server and a Pfw on the ports 20,21, 60000 - 60100.
