When a connection requests the server to transfer files in PASV mode, an external IP address can be specified for security purposes. If the Server is running inside a firewall or other secured environment, an IP address that is externally accessible is required. The range of data connection ports can also be restricted to specific minimum and maximum values.

The page layout of the HTTP/S based web file transfer interface that allows file transfer using a web browser can be customized using a template file in the enterprise edition (Figure 5.10).
