IPSec Mikrotik-Fortigate not working

Hi!
i’m new to this forum, nice to meet you guys,
i’m having an issue establishing ipsec tunnel between my mikrotik (RB1100x4) and Fortigate (80C),
im using guide provided here (http://www.fastbit.ro/en/ipsec-site-to-site-vpn-between-fortigate-and-mikrotik/) but seems to no avail,
i received attached error,
anymore error/config you need me to attach here?

Hello,


That guide you linked is very old. Both RouterOS and FortiOS have had major IPSEC changes.

As you have a Phase1 error I would check the basics, e.g. the auth parameters match, as well as the pre-shared key.

Also, are you intentionally meant to be using NAT-Traversal ?
