To rule out ISP-related issues, try pinging the peer IP from the PA external interface. Ensure that pings are enabled on the peer's external interface. If pings have been blocked per security requirements, see if the other peer is responding to the main/aggressive mode messages, or the DPDs.
It is very important to specify the phase1 name, if you forget to specify this the Fortigate will flush ALL tunnels. You can also reset a tunnel, in this case the Fortigate will completely re-negotiate the IPSec VPN. As with the Flush do not forget the phase1 name or you will reset all your tunnels.
The current configuration is assigned to the root
VDOM. On
FortiGate 60 series models and lower, VDOMs can only be enabled using the
CLI.
Enable multi VDOM mode
- On the FortiGate, go to System > Settings.
- In the System Operation Settings section, enable Virtual Domains.
- Select Multi VDOM for the VDOM mode.
- Click OK.
4) If Phase-2 is still not up, run the packet capture on port 500/4500 and run the below commands,
- # diagnose vpn ike gateway list (or diagnose vpn ike gateway list name <tunnel-name>)
- # diagnose debug console timestamp enable.
- # diagnose debug application ike -1.
- # diagnose debug enable.
VPN event logs
- Go to Log & Report > Log Settings.
- Verify that the VPN activity event option is selected.
- Select Apply.
To clear a session, first we must configure the filter so that we only delete the sessions we want. Without creating a filter then the clear command will delete all sessions.
IKE phase 2In IKE phase 1, two peers will negotiate about the encryption, authentication, hashing and other protocols that they want to use and some other parameters that are required. In this phase, an ISAKMP (Internet Security Association and Key Management Protocol) session is established.
The FortiOS Intrusion Prevention System (IPS) combines signature detection and prevention with low latency and excellent reliability. With intrusion protection, you can create multiple IPS sensors, each containing a complete configuration based on signatures. Then, you can apply any IPS sensor to any security policy.
DPD is a ike status check depending on how you have it configured ( idle or on-demand )based on if ESP data grams are not being sent from the peer. The Phase2 down could be a IPSEC SA clear or admin-down. The DPD down is simple put that the peer has not responded is marked down and ike/ipsec SA are cleared.
VPN delete? Select menu [Virtual Private Network]-[IPsec Tunnel], and click the associated number. ? Pop-up window to select a static route, click [Delete]. ? A confirmation prompt will appear, click [OK], the associated static route will be deleted, and the black hole route will not be deleted.
Nat Traversal, also known as UDP encapsulation, allows traffic to get to the specified destination when a device does not have a public IP address. This is usually the case if your ISP is doing NAT, or the external interface of your firewall is connected to a device that has NAT enabled.
The concept of a security association (SA) is fundamental to IPSec. The security association is the method that IPSec uses to track all the particulars concerning a given IPSec communication session. You will need to configure SA parameters and monitor SAs on Cisco routers and the PIX Firewall.
Fortinet Firewall Management Interface Access Over WAN
- Step 1: Allow HTTPS on Management Interface. On GUI, Network > Interfaces, on Administrative Access section, allow HTTPS.
- Step 2: Permit Public IP Addresses.
- Step 3: Change default https port to 444.

From the VPN Client Node machine:
- Open up the command prompt in Windows.
- At the command line type : ping 192.168.6.1 (Where 192.168.6.1 is the LAN IP address of the VPN Participant machine on the remote side of the VPN) The response should be: Pinging [192.168.6.1] with 32 bytes of data.
