Passive mode on the client side.
Passive mode basically means that the server does not try to open up
a second channel back to the client. The NAT stuff can only handle
this sort of thing if it can recognise the ``PORT'' command going out
on the original channel (it then prepares itself for the
back-connect), but natd only looks for PORT commands on the standard
ftp port.
