Dears,

Hope you are doing well.
I configured my Mikrotik hex lite RB with the below, it worked normally with all the configurations.

My issue is that I have connected the ether3 to the Fortigate wan1 port and I put one of the public IPs on the wan1 interface, the internet worked normally on my local and wireless network but I can’t access the Fortigate device from outside my site with this public IP.
Can you please help me to solve this issue?

Best Regards,

I can’t say about RIP part, I don’t know much about that. Only in firewall, when you drop all incoming packets on pppoe-out1, then allowing something after that is useless, because it will never get there (so you need to swap those rules). Other than that, I don’t see any problem.

Dears,

I swapped this rule with another one, I permitted all input access to the PPPoE-out1, and still didn’t work

Ok, I lied. Not intentionally, I probably got misled by RIP and overlooked the obvious. If you want to access something connected to public-ip-lan interface from outside, of course you need to allow it (this will allow full unlimited access, you may or may not want to limit it in some way):
