Port 21 is what you connect to ftp servers with and port 20 is what they
connect to you with (when not in passive mode). Block it.

I can't afford to be a member of the "API of the Month" club.
Don't get me wrong, I like knowing more than one way to do something,
but I prefer that most of those ways still work a few years after
I've taken the time learn them. Otherwise I'm wasting my time, and
I'm already too good in that regard to need help.
