Site-To-Site VPN between 2 Fortigates auto recconect

Dmityr · ‎09-06-2018

Hello! I created Site-To-Site IPsec VPN between 100d and 61e.

But once in each day it goes down.

I looked at Log&Report at VPN Events and saw that phase 2 IPSec is down.

Does anybody know how to solve this problem?

In the phase2 config, button 'Advanced', you can enable 'autonegotiate'. Strictly speaking, one side should do but it doesn't harm if you enable it on both sides of the tunnel.

Phase1 autonegotiate apparently is already enabled.

Ede Kernel panic: Aiee, killing interrupt handler!

Solved!

Problem was in autonegotiation at phase 2.

1. diagnose vpn tunnel list - and copy the name of our vpn tunnel on each of 2 fortigates.

2. Do this commands with appropriate VPN tunnel name on each of fortigate:

config vpn ipsec phase2-interface edit <name> set auto-negotiate enable end
