Where is ip_vs_ftp.o ? In 2.4 you need ip_vs_ftp.o loaded
to use NAT-ed real servers.
The FTP command/status conn work but not the FTPDATA
connections. In these outputs I see that the command connection works.
When you start ip_vs_ftp the ftpdata connections have to work too.

RTFM first :) man ipvs/ipvsadm/ipvsadm.8, search for "ftp"
