The firewall blocks the server’s attempt to communicate with the client because the server uses a different port than the first connection. Network Address Translation (NAT) configurations block this connection request. In active mode, the FTP server responds to the connection attempt and returns a connection request from a different port to the FTP client. When you use a passive mode session, however, the data port does not always use port 20. During a typical active mode session, the command port uses port 21 and the data port uses port 20. Active and passive mode sessionsįTP uses a data port and a command port to transfer information between a client and a server.

If you use the nftables, firewalld, or iptables applications for your firewall, you must enable firewall settings for the passive ports manually. If you use the ConfigServer Security & Firewall (CSF) firewall plugin, the system also adds passive port ranges to your server’s firewall by default. In cPanel & WHM version 60 and later, the system enables passive ports 49152 through 65534 for Pure-FTPd servers and ProFTPD servers by default.
