Copy files on the same FTP server

[Nobel]

Hi

I have a Synology NAS server on my LAN and I can in FlashFXP log on to the drive using FTP on the left and on the right site on the same time. I then can move/copy files from one folder to another on the Synology server.

When I then log on my Synology NAS server on my office (via the internet) and try the same, the process stops, just after I has startet. (se log)
I have in the firewall open port 20-21 and 55536–56559 and can use the Synology NAS server fine to copy to and from via FTP to my PC, but the “intern” work where I move files from one folder to another on the Synology NAS server dose not work.

In this exempel I try to copy the file aawsepersonal.exe from one folder to another. But the process stops after STOR… the file aawsepersonal.exe is made but is 0 kb.

What can be the problem?

Regards
Nobel
