String |
Port range used in the server for data transmission. You should also open these ports in your firewall. By default the range is 60000 to 60500 and they have to be separated by a colon. You have to restart OpenKM after changing this parameter. 60000:60500 |

CIFS's FTP works better in Passive Mode. So, it might not work properly with file browsers such as Nautilus or Nemo.
Active Mode
When set to active mode, the server will try to establish a connection to a client-side port chosen at random. Since this port is not likely to be one of the predetermined ports, the firewall will block any attempt to connect to it, resulting in no connection being established.
Passive Mode
A passive configuration will not have this problem since the client will be the one initiating the connection. Of course, it's possible for the server side to have a firewall too. However, since the server is expected to receive a greater number of connection requests compared to a client, then it would be but logical for the server admin to adapt to the situation and open up a selection of ports to satisfy passive mode configurations.
