Here are some configuration options:

max_per_ip might help if they're trying to connect multiple times at once

I say this because I'm suspecting that this is a DoS attack, not a crack 
attempt.  First, there is no attempt at using a username or password, 
and second there is a known vulnerability to this in a previous version 
of vsftpd.

Also if you're using xinetd, you might want to see if there's a way it 
can handle these particular configurations you are looking for.
