By default, FTP passive mode doesn't work with the Plesk Firewall.
To work around that on RHEL/CentOS/CloudLinux you need to edit /etc/sysconfig/iptables-config and change the line with IPTABLES_MODULES to:
IPTABLES_MODULES="ip_conntrack_ftp"
It would be better to have an option in the Plesk firewall module to do it there, instead of having to do it manually.
