FTP server using passive ports
Hello everybody. This is more of a network-question than a readynas one. I've just recently bought an Ultra 4 in an addition to my Duo. I've had, and still have the FTP service running at the Du...

Thanks again for the answers
Not so long ago I had a problem with port 21. My router did strange things with the FTP commands sent through this port. I have changed command port to something completely different on the server and forwarded the same port on the router. Since then I have no problem with FTPing from outside of my LAN.
