I understand port forwarding in general … as setup on a router. But what does the port forwarding setting do on MC? The option is available for HTTP, HTTPS, and the 2 FTP ports. A scan is involved by default, but there is also a manual definition where the internal and external ports are specified.
The reason I ask: I am trying to enable the FTP server on my MC device - accessed only from devices on my LAN. (I do not want any access from the internet.) I can get at the FTP server from multiple FTP clients on my PCs, but not from the Acronis True Image built-in FTP client. A WD technician said I need to enable port forwarding on my router and on MC. I’m pretty sure I do not, but I thought I should find out what the port forwarding setting on MC actually does.
