I have very strange problem with creating of IPsectunnel VPN between Mikrotik and FortiGate100D. I can also see Fortinet as establishedunder Active Peer on Mikrotik, but in Policies tab i can see problem: no phase2. I have used the above command in the the FortiGate CLI at Data . Presumably if you don't want it to come up then just change the peer IP to something else. Cisco, Juniper, Arista, Fortinet, and more are welcome. I have used the above command in the the FortiGate CLI at Data Centre site and from the debug output I have observed that there is a Preshared Key Mismatch from logs. Step-1 ( Verify L2/L3 Connectivity btw Peers):( Refer Pic_1)In the GUI of FortiGate NGFW I observed that IPsec VPN status is Inactive. Use the FortiGate VPN Monitor page to see whether the IPsec tunnel is up or can be brought up. IPsec uses UDP Port No-500(Without NAT) and 3500(With NAT) for establishing tunnel. Some are essential to the operation of the site; others help us improve the user experience.
