IPSec native win client

Deftone · ‎12-08-2021

Hi,

I just upgraded my 100E to 7.0.3 OS release.

What I see is that the dial up IPSec created with wizard for native win client doesnt work anymore?

I can connect but can not reach anything on the other side.

When I roll back to 6.4.8 everything is working fine again.

Any idea what has changed and how to resolve it? I have all policies set

Hello,

It is not clear from your notes if you are using IKEv1 or IKEv2 with the Windows Native Client. But, I am assuming you are using L2TP over IPSec (which uses IKEv1) and that needs some manual configuration change as mentioned in the below document after upgrading device to FortiOS 7.0.3
