Hi, I have tried to use USG20-VPN as an IPSec client to corporate SeGW, but no success. Even though I know the pre-shared key is correct, IKE_Log always shows Authenticate failed. Here is the detailed IKE_Log.

Can someone shed some lights on how to configure USG20-VPN as an IPSec client using IKEv2?

    To build VPN tunnel between USG20-VPN and other firewall/gateway, you need to adjust some parameters on both devices to make it work.
    We need more information to check why the VPN tunnel is not established.
    I will send you a private message and let you know what information we need.
