IPsec IKE v2 Config

Hi Team,


I have IPsec IKE V1 remote access and I need to change it to V2.

After changing it to V2 I didn't connect to the tunnel giving the below warning in logs:

No response from the peer, phase1 retransmit reaches maximum count

Note that we uses Forti authenticator with FortiGate.


My Config:


set type dynamic
set interface "IPSec"
set ike-version 2
set peertype any
set net-device enable
set mode-cfg enable
set proposal aes128-sha256 aes256-sha256 aes128gcm-prfsha256 aes256gcm-prfsha384 chacha20poly1305-prfsha256
set dpd on-idle
set idle-timeout enable
set idle-timeoutinterval 60
set ipv4-start-ip 
set ipv4-end-ip 
set ipv4-netmask 
set dns-mode auto
set psksecret


What is the problem ?

Could anyone help me ?


after entering the token it gives VPN connection failed in forticlient but no error in FAC.


May because the client uses EAP-GTC as shown in the above pictures ?


Note that the failure from FG debug as below:

The last update that I configured the tunnel  and I can connect but without internet.

My policies include groups but when I remove those groups and replace them with "All" I'm able to connect.

In my environment I don't need to remove groups from polices.

Is there a solution for this issue?

In the tunnel config there is a command should specify( set authgrp " "), I've added one group but how do I add multiple groups ?
