ARMOR Z2 NBG6817 firmware download

azaz

Hello,

I'm trying to download the latest firmware of the NBG6817 but :

• I can't find it on the end of life product download
• I tried a wget to ftp://ftp2.zyxel.com/ARMOR_Z2_(NBG6817)/firmware/ARMOR%20Z2%20(NBG6817)_V1.00(ABCS.11)C0.zip without sucess and I found it's not allowed since 2021.
• I tried a wget to "https://download.zyxel.com/ARMOR_Z2_(NBG6817)/firmware/ARMOR%20Z2%20(NBG6817)_V1.00(ABCS.11)C0.zip" but still no good !

Any idea how I can retrieve it ?

Thanks,

Regards.
