    L2TP VPN on our smartphone is able to be established to ATP200 (Firmware: 5.10(ABFW.0)).
    - Android 11
    - Xiaomi Mi A3


    We suggest you follow the wizard on the USG/ZyWALL/ATP/USG FLEX to configure L2TP VPN.

    I recently used an Android 11 phone (Moto G8) with a ZLD 4.65P1 firmware without any issue...
  • Hello everybody,

    Thanks for your help.

    The problem is that ia have a Zywall 310. You think, it's compatible with L2TP VPN, Android11 and an Oppo Find X3 Pro  ?

    Best regards
