I have a Zywall 110 device with 4.11 firmware. I want to update my firmware to 4.33 last version.

1) If I update the firmware, will the Zywall 110 current settings be deleted to the factory settings?

2) does i need first update from 4.11 to 4.20, and then to 4.33 or i can directly update from 4.11 to 4.33 version of firmware?

    Zyxel_Cooldia says "we would suggest to follow the firmware upgrade path V4.11 -> V4.15 -> V4.20 -> V4.25 -> V4.30 -> V4.33."

    Hi Zyxel_Cooldia - where can I download the legacy firmware versions? My portal gives me access to the current v4.35 and 4.33. Where can I download your recommended V4.15, V4.20, V4.25, and V4.30?
