When you use ISPmanager to upload and download files from a domain, passive FTP can be a very practical and simple option since this panel is configured for its use by default.
By default, passive FTP in ISP is already enabled, and the server’s Firewall, in our image, allows all traffic. The only thing you need to do is add the ports that come pre-configured in ISPmanager 50000 - 50100 in the Clouding Firewall.
Configure Passive Mode
Once you have created the user, you only need to configure the Clouding Firewall rules. Go to your Clouding account, navigate to "My Firewalls," select the profile your server is using, and add the following Firewall rule:
Once this is done, you will be able to access your FTP user with passive ports more efficiently and securely.
If you want to use FTP and you don't know how to create users, you can go to the following link: How create FTP Users with ISPmanager
