  - Log in to the server as the root user via SSH - Take a backup of the configuration file #cp /etc/pure-ftpd.conf /etc/pure-ftpd.conf-backup
  - Open configuration file /etc/pure-ftpd.conf #vi /etc/pure-ftpd.conf
  - Search PassivePortRange
  and update the port range you want. PassivePortRange 49152 65534
  - Restart the service for changes to be effective #systemctl restart pure-ftpd.service

  I had tried it before but whenever we restart the port range was changing to default values

  Try: #echo "PassivePortRange: 49152 65534" >> /var/cpanel/conf/pureftpd/local #/usr/local/cpanel/scripts/setupftpserver pure-ftpd --force
  NOTE: Replace the port range you want.

  Please check if your server had any firewall which is causing issue try to stop server firewall and then try again.

  Sure - you can set them to any range you want. You'll just need to make sure you open them in the server's firewall as well.
