IPSEC S2S Issues

[Math43]

Hello,

I've got issue with a IPSEC tunnel site to side between Opnsense and Fortigate.

Here is my setup:

NET A <-> FORTIGATE <-> WAN <-> OPNSENSE <-> NET B

I can access NET A from NET B but I can't access NET A to NET B.

On my Fortigate I see packet going through corresponding IPSEC but I see nothing on Opnsense side (with tcpdump).

What could possibly be wrong ?

Thanks a lot.

Regards,
Mathieu

Missing firewall rules?

My firewall is configured to accept any packet on ipsec interface.
