It seems like GL NAS feature not encrypted

Just make encryption mandatory, is it that hard?

sed -i '/\[global\]/a \   smb encrypt = required' /etc/samba/smb.conf.template

Hi

Could you please clarify your device model and firmware version?

Starting from firmware v4.8, Samba encryption should already be enabled by default.

Mudi v2, Spitz v2, Beryl AX: 4.7, 4.3, 4.7

As mentioned earlier, we introduced this change starting from the v4.8 firmware.

Therefore, you may want to

  • consider upgrading your device to a v4.8-based firmware version for out-of-the-box support,
  • or alternatively SSH into the router and manually adjust the settings as you mentioned previously.
