It works beautifully with Serv-U ftp server version 4:
227 Entering Passive Mode (192,168,1,20,4,149)
As long as the passive ip is set to be the real ip of the ftp server, not
the VIP. Maybe this should be documented somewhere? Or maybe it is and I
just didn't read carefully enough :)

It should work for NAT without persistence as long as the
ftp daemon is using the "227 Entering Passive Mode (" response.
This is how the ip_vs_ftp is working now, so far nobody proposed
alternative way to properly handle the response strings.
Some clients have "debug" command to display the raw FTP talks,
others display the responses without any debugging. Can you guys
check whether your real FTP servers reply with such response?
Or to check with tcpdump -x -s 2000 whether the message is
received in one packet. If the ftp module can not detect the
real server response then the data remains unchanged and by
this way the client is confused.
