I agree you'll need do passive mode ftp if you're just using the binary
port.  In general I haven't found getting a client to do it to be a
problem, but obviously my mileage varies from yours :).  I suspect most
modern clients do it well as firewalling is becoming more common, but
I may be incorrect.

In terms of the networking package, here is a good chance to convince the
original poster to maybe update it :).
