Forti/MicroTik IPSe issue

[ThePro]

Im trying to setup an IPSec VPN between an Forti (my side) and an MicroTik.

You are seeing 192.168.1.101 (thats the local IP for the Forti) because theres a DMZ from the ISP modem/router to the Forti. I have other VPNs with other Fortigates and Ciscos on this same Forti/Site and they are running just fine.

Apparently Im getting an erro during Phase1

no, phase2 is not negotiated successfully. Check the local/remote subnets (quick mode selectors), and then the encryption settings. I'd choose only one set, like SHA256/AES256.
