A little more details would be helpful. But can you explain what/where the diagnostics fails?

 

PSK mismatch ? ( are you 100% sure PSK are correct on peers )

Acceptable Proposals ? ( 3des. aes128 192 256 or what ? )

ProxyID matches issues ? ( do they match peer 2peer )

fwpolicies issues ? ( is the policies correct, is the ordering correct )

is the vpn rt-based or policy-base ? ( if it's the former do you have routing confirmed ? )

Hello , 

I followed the exmple in the url bellow 

http://docs-legacy.fortinet.com/cb/html/index.html#page/FOS_Cookbook/IPSec/cb_ipsecvpn_fgt_basic.htm... 

 

8-  Go to Policy > Policy > Policy and select Create New to add a security policy for the IPsec VPN.    Source Interface/Zone internal Source Address HQ_net Destination Interface/Zone wan1 Destination Address Branch_net Schedule always Service ANY Action IPSEC VPN Tunnel HQ_to_Branch_p1

In this exemple, i created the phase 1 and phase 2 (HQ_to_Branch_p1  and HQ_to_Branch_p2 )

but the VPN tunnel does not appear in the choices

Why, 

Thank you in advance.

For most of the newer firmware releases, the GUI defaults to creating an interface-based IPsec VPN in Phase 1. You'll need to expand the Advanced section, and deselect Enable IPsec Interface Mode in order to use the Phase 1 in your action IPsec policy.

in th HQ i used the following configuration: 

 

PSK mismatch ? ---> there is no mismatch in preshared key. Acceptable Proposals ? ---> Encryption : aes256 Authentication: SHA1                                       DH Group : 5                                        Keylife : 28800 ProxyID matches issues ? ---> I have this in : Quick Mode Selector :                         Source address: 10.10.10.0/24                        Destination address: 192.168.1.0/24  fwpolicies issues ? ---->             Source Interface/Zone: internal             Source Address: HQ_net             Destination Interface/Zone : Branch_net             Destination Address             Schedule: always             Service: ANY             Action: IPSEC             VPN Tunnel: HQ_to_Branch_p1 is the vpn rt-based or policy-base ? --->             I use a static route with the following             IP/Mask : 10.10.10.0/24              Gateway : 10.10.10.1             Distance: 10              Priority: 0                         I use a static route with the following             IP/Mask : 0.0.0.0/0              Gateway : 172.20.120.200             Distance: 10              Priority: 0

it is good configuration or not ?

thank you in Advance?

Okay sorry for the tardy reply but based on the rt-based vpn and the next-hop I believe you have a problem.

is the vpn rt-based or policy-base ? --->             I use a static route with the following             IP/Mask : 10.10.10.0/24              Gateway : 10.10.10.1             Distance: 10              Priority: 0          

 

if your have rt-based your destination address should be pointed thru the named "phase1-interface"

 

Can you post your cfg?
