Not an answer, per se, but an option. And not even a very good one.

You might try installing an FTP proxy on your machine running ipfw... that
is, if your anti-virus program allows that to be configured. If it won't
let you choose passive mode FTP, it probably doesn't. That's pretty weak.

Cheers,

Thomas
