pure-ftpd Setup Passive FTP Ports

How to enable passive ports on your pure-ftpd server and CSF Firewall
When transferring files on/from your ftp server you will need to have passive ports specified and allowed in the firewall.

Firstly lets edit pure-ftpd configuration file
Uncomment (remove # at beginning of the line) PassivePortRange and specify the passive port range:
* If this line is missing then simply add it at the end of the file.

Restart pure-ftpd to load the new configuration

Next steep is to set the CSF firewall configuration
In file /etc/csf/csf.conf add the same port range under TCP_IN and TCP_OUT

In lines TCP_IN and TCP_OUT add 30000:50000, example

csf -r
