Hello Everybody,

Since i change my smartphone, I can't connect on the L2TP over IPSEC vpn anymore. 

My smartphone config:
- Android 11
- Smartphone Oppo Find X3 Pro (ColorOS 11.2)

The VPN Config : Like this guide searchArticle!viewBlob.action (zyxel.com)

The question is : I am alone with this problem :-) ?

Thanks a lot for your help

Hi @virtuOS,

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 to avoid mis-configuration.
