Passive FTP Port Range:
You can use the default port range (55536-56559) or specify a port range larger than
1023. When using this function, make sure you have opened the ports on your router or
firewall.

When passive FTP connection is in use, the FTP server (NAS) is behind a router, and a
remote computer cannot connect to the FTP server over the WAN, enable this function.
When this option is turned on, the NAS replies the IP address you specify or
automatically detects the external IP address so that the remote computer is able to
connect to the FTP server.
