Setting Passive FTP Mode for ActiveTransfer Server
ActiveTransfer Server can work in both active and passive FTP modes.
In active mode, the server creates an outgoing connection through the specified port to the client machine for data transfer as specified in the FTP commands issued by the client.
In some cases, such as when firewall impose restrictions on connections, it is not possible to create an outgoing connection to a client machine. In such cases, passive FTP mode is used, and the client initiates the connection to the server specified from the range of port numbers that can be used for such a data connection.
To set passive FTP mode for
ActiveTransfer Server1. In My webMethods: Administration > Integration > Managed File Transfer > Server Management.
3. On the Ports tab, select an FTP port from the list of ports.
4. In the Access section, for the Passive Port Range in the From and To boxes, specify the range of port numbers that can be used for passive port connections.
Note: Be sure to provide proper access for the ports in your firewall settings. Otherwise, connections between the client machine and ActiveTransfer Server might be blocked.
5. If your firewall or router is FTP-aware, select the Router/Firewall Aware check box.
Note: FTP-aware routers and firewalls will inspect the FTP command and response, and might modify the response. Check your firewall configuration before selecting this option.
6. In the Passive IP Address box, do one of the following:
If you want
ActiveTransfer Server to automatically assign the IP address or host name of the server based on the listener configuration, type
Auto. Ensure that you specify the IP address or host name while creating data connections in passive mode.
If you want to enter an IP address manually, type the IP address to use for the passive IP address.
7. In the Welcome Message box, type an optional welcome message. If specified, this message appears in the FTP, FTPS, and SFTP client console when a user connects to the server.
