FTP server handler properties to control communication with FTP client

Options that control the communications with an FTP client when there is an intervening load balancer or firewall.

Disable passive data connection (PASV) IP security check

When a client requests passive mode through the PASV FTP command, the FTP server sends a response to the client. The response contains the IP address and port that the client must use to initiate the FTP data connection. When the FTP server accepts an incoming connection, the FTP server runs a security check that verifies that the incoming data connection comes this client. This option disables this security check.

Note: This property is supported on only the Multi-Protocol Gateway or Web Service Proxy.

Use alternate PASV IP address

In passive mode, the FTP server can advertise an IP address other than the default FTP server address for client connections. This advertisement might be useful when there is a load balancer in front of the FTP server and the client cannot directly reach the IP address of the server. When you enable this option, you can configure the numeric IP address that is advertised to the FTP client.

Note: This property is supported on only the Multi-Protocol Gateway or Web Service Proxy.

Disable active data connection (PORT) IP security check

The FTP server connects to an IP address and port that is specified by the client to initiate the FTP data connection. Before the server connects to the address, the server runs a security check to verify that the IP address is the same address that initiated the control connection. This option disables this security check.

Note: This property is supported on only the Multi-Protocol Gateway or Web Service Proxy.
