Which version of FileZilla are you using?

What server software product and version are you using?

I have the same problem with normal FTP connections to a PROFTPD server. I see the same error messages on my own Proftpd server and someone else's.

Here's some details that original submitter didn't include:

• Server OS Ubuntu running the 2.6.31-21-server kernel
• FZ client version 3.3.2.1
• FZ client running on Win XP, Win 7 (same issue on both OSes)
• ProFTPD Version 1.3.2

Here's the FZ ouput:

Response: 220 ProFTPD 1.3.2 Server (XXX) [XXX]

I'm seeing this happen after I enable Active file transfers too BTW, happens on the PORT command. 1/3 of all files I try to upload fail and must be retired... so it takes about 20 tries to upload all my files :(

I've modified the log to remove reference to client and server machine details/files.

Definitely a router and/or firewall that is interfering with the connection.
