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 is easier to use and is more firewall and NAT router friendly.
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 command channel between the FTP server and the client by sending the PORT command to TCP port 21, The server will respond by connecting to the specified client data ports on its local port, typically TCP Port 20.
This connection process works unless the FTP client is behind a firewall. In this scenario, the client’s firewall will prevent the FTP connection request to arrive from the server.
One way to solve this problem is to change the client's mode from active to passive. 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, a client sends an PORT command in order to establish a data channel with the FTP Server. 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. This is often done to protect against unauthorized access, but can also cause problems when using FTP.
Network Address Translation Devices (NAT) can also be used to protect from unauthorized access. These devices enable multiple computers sharing a single address. However, they can act as firewalls to block connections from the outside. NATs are particularly good at blocking connections to internal servers, but can be difficult to configure for 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 the client initiates the control on port 21 but instead of sending the PORT command it sends the PASV command. This command tells FTP to send the client an IP address with a port number.
If the Automatic Passive Mode is enabled in Fetch and an error occurs when Fetch tries to connect to a server, Fetch will automatically switch to passive. If this doesn’t work, select the Passive Mode option under the FTP Setting Menu.
Clients can choose between active or passive mode, though passive mode is usually better for NATs and Firewalls. The client may be configured to use only a small range of high port numbers on the host, which limits the number that can potentially be blocked by the firewall. This will also decrease the risk to the server from a firewall that may block all traffic on a high-level port, but will not remove all of the security issues associated with a firewall.
