Route LAN over VTI interface over IPSEC Tunnel

Hello,
I am setting up a VPN tunnel between a Fortigate and a stormshield using a VTI to mount IPSEC (Phase 2).
Below is my architecture

Sans titre.png

 

The tunnel is well assembled and UP (phase1 + phase2)
Phase-2 is mounted on the VTI (architecture constraint) . I want to communicate between my 2 remote LANs
I configure a sercurity-policy to manage my trafic and configure static route that goes to reach the LANs behind each firewall. 

Traffic can't pass. After debug, the packet always stops at phase-2 on the fortigate side.
I would like to know how to make my VTI a network gateway to be able to route my current LAN and my future LANs.

Or I want some feedback of someone who build VPN with Fortigate and stormshield using VTI as gateway

Sincerely

Hello @NRA,

Can you provide the debug flow for the traffic when replicating the issue as well as the VPN details on the fortigate?

di vpn ike gateway list name <tunnel_name>
di vpn tunnel list name <tunnel_name>

We will need to see how fortigate is processing the traffic.

Kind Regards,

Hi @NRA,

 

Can you collect debug flow and share the outputs? Please refer to this article: https://community.fortinet.com/t5/FortiGate/Troubleshooting-Tip-First-steps-to-troubleshoot-connecti...
