Some FTP programs default to “active” mode, which can cause problems with Key connection type “Layer 3 – routed”.
Possible solutions:

  • Change FTP program to use Passive FTP mode instead of Active FTP mode. This setting is at least available in Total Commander for Windows.
  • If unable to change to Passive mode, you can change TOSIBOX® Key connection to Layer 2:
  • Open Lock Web administration interface
  • Log into the Web UI as admin
  • Open Status view (the default view)
  • Click Edit Tosibox Connections
  • Scroll down the page to find the Key you’re using to connect
  • Change the Connection type option from “Layer 3 – routed” to “Layer 2 – bridged”
  • Uncheck the “Prevent connections towards this Client” checkbox
  • Scroll down the page and click Save
  • Reconnect TOSIBOX® Key connection using Tosibox Key’s Disconnect/Connect button.
