Port IP Mode > IP Repeater
When the "Port IP Mode" setting is set to "Auto", the IP Repeater is enabled.
This feature will attempt to assign the correct IP address for the PORT command using an https (port 443) connection to repeater.smartftp.com to get the external IP.
This feature should only be enabled if the NAT router does not replace the internal IP in the PORT command with the external IP. This is usually the case when the connection is made to a port different than the standard FTP port (21).
