Seems, that her ftp-data connection seems to go out thru another uplink
then the control connection. Most ftp-servers denies this
(site-to-site) transfer mode.
I don't know any available solution to this problem, except to route all
ftp-traffic (data and control connection) thru a specific device.
For this you need to select all ftp-packets (iptables) and route them
thru one of your uplink devices (simple ip rule add fwmark ... stuff)
For non-pasv ftp-transfer mode it's possible to implement a patch to the
ftp-nat-helper module for selection proper (means the same) uplink
device under respect of uplink device from control connection. But so
far there is no patch i know about.
