Is the ftp access blocked on the new firmware of Ewon flexy ?

Last Updated 12 days ago

Yes, the FTP server behaviour has indeed changed in the latest Ewon Flexy firmware:

Starting with firmware version 15.0 (released to comply with the EU’s Radio Equipment Directive as of 1 August 2025), the FTP server is now disabled by default (both after factory reset and on fresh units). It is also no longer available on the WAN interface; it can only be enabled on the LAN and/or VPN interfaces via the ClosedDevice parameter .
A similar change applies to Firmware 23.0 for the Cosy+ model (and likely consistent with later Flexy firmware updates): FTP remains disabled by default, and can only be selectively enabled for LAN and/or VPN access .

Firmware Version	FTP Default State	Interface Access Restricted?	How to Enable
15.0 (Flexy/Cosy131)	Disabled	Yes (only LAN/VPN allowed)	Set `ClosedDevice` via tabular editor
23.0 (Cosy+)	Disabled	Same restrictions	Same method via `ClosedDevice`

To re-enable FTP on LAN and/or VPN:

Log into your Ewon Flexy’s web interface.
Navigate to Setup → System → Storage → Tabular edition → COM cfg.
Adjust the ClosedDevice parameter to the appropriate value:
- 21 – FTP server closed on all interfaces (factory default)
- 0 – FTP (and HTTP) server open on both LAN and VPN
- 1 – FTP closed on LAN, open on VPN
- 16 – FTP closed on VPN, open on LAN
Reboot your device to apply changes.
