You may need to change the default FTP port 21 to any other port like 1234 for security reasons.

We'll provide a step-by-step tutorial on how to change the pure-ftp port on a cPanel server.

cPanel provides an easy way to update pure-ftp config from this file: /var/cpanel/conf/pureftpd/local

1. Login to SSH as root
2. Edit the config file with nano or your preferred editor # nano /var/cpanel/conf/pureftpd/local
3. Add Bind: 1234 to the file (where 1234 is the new port number)
4. Press CTRL+X then press Y and Enter to exit and save.
5. restart FTP using this command/usr/local/cpanel/scripts/setupftpserver pure-ftpd --force
6. Finally, add the new port to the firewall

If you use firewalld on CentOS 7, use the following command to open the port 1234:

$ sudo firewall-cmd --permanent --zone=public --add-port=1234/tcp

restart firewalld 

$ sudo firewall-cmd --reload

If you use CSF, find the config file and open it with nano or your preferred editor

$ nano /etc/csf/csf.conf

Find TCP_IN line and remove the old port number and replace it with the new port or add the new port at the end of this line like:

TCP_IN = "80,443,465,21,22,587,993,25,53 ... ,1234"

Restart CSF using this command

$ csf -r
