Hello. I have 2 servers both running Serv-U 4.1 in Implicit SSL mode (Allow only SSL/TLS sessions). I can upload/download from my workstation to/from any of the two servers without any problem and I can see the icon with yellow padlock in Serv-U's Activity window during transfer. I can also send file from ftp.smartftp.com, connected in Explicit SSL mode, to any of the two servers and the data channel is encrypted with the yellow padlock shown. The problem occurs when I send file between the two servers. It is not encrypted. Prior to transfer, I can see that SmartFTP issues PROT C command (it doesn't in previous case). That's probably why the data transfer is not encrypted. But I don't know why SmartFTP has to issue that command. Any ideas?
