I wasn't running the ip_masq_ftp module, but after loading it, it doesn't
seem to help
my problem, although now I can ftp out from  my realservers.

The problem is running ftpd on the realserver and connecting to it from the
client who is behind a firewall.  To verify it wasn't the firewall causing
all the problems, I tried running the ftpd right on the director box (on the
VIP), short circuting the realservers and LVS, and that worked the way it
should.

do you have the ip_masq_ftp.o module compiled/loaded?

is that the director==LVS==VIP or to the real-server?
