When i ask you what is your config, i mean you must explain
what OS you use, what kernel you use, if you work in LVS-TUN, 
LVS-NAT or LVS-DR.....

Ftp is not a simple protocole. you log on port 21 (Authentification)
and the data are sent in Another port. There is two methods: Passive FTP
and Active FTP.

To make ftp work with LVS, you must load ip_vs_ftp in the kernel
or like a module. Did you do that?
