FTP passive vs. active is a consideration that most users should take into account, especially if their FTP client is being used behind a security firewall. Passive mode FTP makes it easier to use. It is also more friendly with firewalls, NAT routers, and other security measures.
FTP, or Internet protocol (IP), is an IP that allows files to move between computers by using a server and a client. FTP protocol is made up of a command and data channel. These channels are used for transmitting information from the client to the server.
The client initiates an FTP command channel by sending TCP port number 21 as a PORT. The server connects back to its local dataport, usually TCP 20. This is the port specified by the client.
This connection process will work as long the FTP Client is not behind a Firewall. In this scenario, the client’s firewall will prevent the FTP connection request to arrive from the server.
The client can be switched from active mode to passive mode to fix this issue. In passive FTP mode, the FTP server still initiates the channel of command but sends a PASV instead. The FTP client replies to this command with a random data port that it has open for the file transfer.
In Active Mode, the client will also send a PORT to initiate a data channel between the FTP server and the client. However, this is a reverse data channel, and not as firewall and NAT router friendly as passive mode.
Firewalls can help secure networks. They do this by only allowing specific types of traffic through certain ports. It's often done in order to prevent unauthorized entry, but this can also create problems when using FTP.
Network Address Translation devices (NAT) are another way to prevent unauthorized connections. These devices allow multiple computers to share a single IP address, but can also act as firewalls when connections come from the outside. NATs can be very effective at blocking external connections, but they are difficult to configure to support firewall support.
The Passive Mode was created in order to remove some of the burden from the client's side when it comes to firewall configuration. In passive mode, a client still initiates a control channel at port 21, but sends a PASV instead of a PORT. This command asks the FTP server for an IP address, port number and data channel to be created by the client.
When you run Fetch on a firewall, and you receive an error when trying to connect, the Automatic Passive Mode will be automatically switched to passive mode. If that does not work you can manually activate the passive mode in the FTP Setting menu by selecting the Passive Mode.
The client can choose active or passive, but passive mode typically works better when using NATs or firewalls. The client can be configured to use a limited range of high-level ports on the server, which will limit the number of ports that can be blocked by a firewall. It will also reduce the risk of a server being blocked by a firewall.
