I think it is interesting to know which error you will be facing if you don’t configure correctly your VPN IPSEC phase 1.

You have to enable debug on your appliance at first :

diagnose vpn ike log-filter dst-addr4 10.189.0.182
diagnose debug application ike -1
diagnose debug enable

Example is taken with fortigate appliance
