Good morning, everyone,
I have found an old Firewall USG20 with firmware 3.30, I would like to use it for testing but I need to upgrade it at least to firmware version ZLD 4.20 to be able to use it. Support is no longer active and I can't find the 4.20 firmware download anywhere, could someone kindly give me a link or a solution.
Thanks

    Hi @Kikko

    The ZyWALL USG20's latest firmware is version 3.30(BDQ.9)C0, and this model reached its End-of-Life (EOL) status in 2018. Unfortunately, as a result, there is no further support or new firmware development available for it.

    For advanced protection and enhanced features, we recommend upgrading to a current firewall model. You can explore our latest offerings here: https://www.zyxel.com/global/en/products/next-gen-firewall .
