It’s possible to change the firmware (Debian Linux) to remove this limitation:
To enable SSH access to the NAS, go to this page: http://your_mbl_address/UI/ssh
In the file “/etc/network/if-up.d/local-net”, comment the following line with a “#”:
# echo “Allow from $LOCAL_NET.” >> “${TMP_ALLOW_FILE}”
and add the following line:
echo “Allow from all” >> “${TMP_ALLOW_FILE}”
Then run the script “/etc/network/if-up.d/local-net” to apply the change.
This change should persist over time and reboot. Maybe a firmware update will require repeat the procedure.
P. S. Use “nano” as a text editor
