Data connection
A data path or circuit between two computers over a phone line, network cable, or other media. options group

Use outgoing data connections (PASV/EPSV)

Checking this box forces all data connections to be originated by SecureFX (using the FTP PASV or EPSV command). This setting is often needed where a firewall will not allow incoming connections from external FTP servers. If the PASV or EPSV connection fails, SecureFX automatically tries to reconnect using the original host/IP address. When this check box is unchecked, SecureFX will have the FTP server create an incoming data connection instead (using the FTP PORT or EPRT command).

This option is on by default. This is used as the default setting for the identical Session Options option.

Disable direct server-to-server transfers

This option is unchecked by default. Checking this option will force all server-to-server transfers to be handled by establishing indirect data connections through the local host. This option is sometimes needed where a server behaves poorly after receiving a request to establish a server-to-server connection.

Limit local ports used for PORT connections

This option, when enabled, allows you to specify a range of ports for SecureFX to use when making an FTP or FTP/TLS data connection.
