it seems there is a bug somewhere in ip_conntrack_ftp, the kernel module,
in kernel 2.6.11 and possibly other versions, that malforms ACTIVE ftp
In the iptables mailing list there are a few patches for fixing ACTIVE ftp
issues in kernel 2.6.12.
I suggest to use PASSIVE ftp in the meantime. I verified that passive ftp
is working correctly. Another solution would be to use a kernel version
that is not affected by this issue.
To enable PASSIVE mode, consult the manual of your ftp client.
