Just to follow up to my previous response - one thing I did think of
that might explain such behavior is if your FTP client happens to use
a certain range of local ports (either via a special local version or
something) that happens to match something configured in your
firewall, but ftplib is picking local ports outside of that range.

If that was the case, you could probably subclass the FTP class,
override the makeport() method and create something that obtained
ports from the same range as your normal FTP client.
