Using an FTP/FTPS Port Range
 
Specifying an FTP/FTPS Port Range
Integration Server provides FTP and FTPS listeners that listen for FTP/FTPS client data connections on any free port. For FTPS, this port usage method requires all ports to be open on the firewall, a situation that firewall administrators prefer to avoid.
You can specify a range of port numbers for the FTP/FTPS listener to use with a client data connection that uses passive transfer mode (PASV). Integration Server provides the following configuration parameters that you can use to specify the lower and upper bounds of the port range:
*watt.net.ftpPassivePort.min
*watt.net.ftpPassivePort.max
