I had a similar problem years ago when setting up a Linux NAT firewall 
for a small company.  The solution was loading the ip_conntrack_ftp 
along with ip_conntrack I believe.

Correct me if I'm wrong (it's been while since I've used FTP).  The 
problem was with the ftp protocol.  Port 20 was for your data transfer 
while 21 was the control port.  If I remember correctly you need both 
modules for this to work properly.

At least it's something to look at.
