The address the server will claim to be listening on for the data port. Useful when the server is behind a NAT firewall and the client sees a different address than the server is using.

This option specifies if the server should check if the IP address for the data connection is the same as for the control port. If the IP is not valid, the connection will fail. If left blank, the default is No.

The ports on which the server is allowed to accept Passive Data Connections. Multiple port numbers are comma delimited. The text box also accepts ranges separated with hyphens. Ranges and single port numbers can be mixed (i.e. 60000-61000, 61052, 63000-65535). Valid port numbers are from 1 to 65535, however many ports below 1024 are reserved by the operating system and other programs.Note: If you wish to Delete a Listener entry, select the Listener entry in the Configuration Outline, then click the Delete link in the page toolbar.
