Other than the answer about your UDP services..

Are you sure the vsftpd PASV mode requires UDP? That would be abnormal.

Normally passive mode with vsftpd (or any FTP server) requires TCP, and
opening up the firewall to allow the range of TCP ports you have specified
in the vspftd.conf file. 

It is only some of the experimental accelerated file transfer
protocols that start playing with spraying UDP packets.
