Organizations are transforming the way they do business in a variety of ways, from creating new operating and cost efficiencies to service delivery methods. As they adopt multiple clouds to make the data and applications that enable these business innovations available wherever they are needed, this new infrastructure unintentionally results in an increased digital surface and exposes data in transit breaches.

Security has emerged as one of the primary roadblocks to multi-cloud adoption that requires movement of data, applications, and services from on-premises data centers to the cloud. Consequently, distributed environments must provide consumption from places such as campuses, branch offices and newly emerged smart mobile devices in a manner that is consistent with established corporate and regulatory compliance secure access policies. Accelerating the on-ramp to the cloud requires a new, innovative approach.

Security-driven networking allows enterprises to architect networks that deliver seamlessly integrated end-to-end security to connect with multiple clouds and implement a cloud-first strategy.

Data Sheets Fortinet Product Matrix.The following procedures include configuration steps for a typical Security Fabric implementation, where the edge FortiGate is the root FortiGate, and the downstream FortiGate devices are all devices that are downstream from the root FortiGate.

The edge FortiGate is typically configured as the root FortiGate, as this allows you to view the full topology of the Security Fabric from the top down. If you select Test Connectivity and this is the first time that you are connecting the FortiGate to the FortiAnalyzer, you will receive a warning message because the FortiGate has not yet been authorized on the FortiAnalyzer.

You can configure this authorization when you configure the FortiAnalyzer. See FortiAnalyzer. The FortiGate will verify the FortiAnalyzer by retrieving its serial number and checking it against the FortiAnalyzer certificate. The FortiAnalyzer serial number is stored in the FortiGate configuration. Downstream FortiGate devices can be securely added to the Security Fabric without sharing the password of the root FortiGate.

Downstream device serial numbers can be authorized from the root FortiGate, or allowed to join by request. New authorization requests include the device serial number, IP address, and HA members. HA members can include up to four serial numbers and is used to ensure that, in the event of a fail over, the secondary FortiGate is still authorized.

When a downstream Fortinet device's serial number is added to the trusted list on the root FortiGate, the device can join the Security Fabric as soon as it connects. After the new device is authorized, connected FortiAP and FortiSwitch devices are automatically included in the topology, where they can be authorized with one click. The administrator of the root FortiGate must also authorize the device before it can join the Security Fabric.

The root FortiGate must have FortiTelemetry enabled on the interface that the device connects to. Use the following commands to view, accept, and deny authorization requests, to view upstream and downstream devices, and to list or test fabric devices:. To disable the automatic synchronization of these settings, use the following CLI command:.

After devices are deauthorized, the devices' serial numbers are saved in a trusted list that can be viewed in the CLI using the show system csf command. For example, this result shows a deauthorized FortiSwitch:. FortiGate The following procedures include configuration steps for a typical Security Fabric implementation, where the edge FortiGate is the root FortiGate, and the downstream FortiGate devices are all devices that are downstream from the root FortiGate.

That is, I do NOT use proxy-ids in phase 2 for the routing decision which would be policy-basedbut tunnel-interfaces and static routes. This applies to both devices. These are the steps for the FortiGate firewall. Refer to the descriptions under the screenshots for further details:. I guess I am missing some configuration on the Cisco side. Well, if the ping in one direction works inclusive the echo-replyyour VPN is woring.

Have you reviewed all policies? Please verify the policies on the Forti for both directions! Hi Johannes, Thanks for your reply. You were right there was a policy issue on the FG side.

All fixed now. Thanks again. Hi Johannes, great post ipsec is up and running. After configuring the cisco router for fotigatec based on above example the protocol goes down every couple of mins. Great post. I only had one issue. Everytime I rebooted the Cisco Ciscomy tunnels would drop. I fixed it by removing the ip unumbered portion and giving it an ip and now it works on reboot.

So my Cisco CLI commands looked like this:. Your email address will not be published. Notify me of follow-up comments by email. Notify me of new posts by email.

Bronze Member. Both sites a running a FortiOS 5. The goal is that devices on Site1 can communicate with devices on Site2, although their ip subnets overlap.

Unfortunately, both don't seem to work or match my requirement.

Overlay Controller VPN (OCVPN)

As for the doc, at the beginning, it sounds like the solution to my problem. But only very late, in "Results", it is explained that Site1 and 2 will actively have to communicate with a mapped ip range.

And the cookbook recipe does not even seem to be complete at all, that is VIPs being created but never used in the recipe. Expert Member. Of course, you will have to create at least one policy from tunnel to LAN into which you insert the VIP as the destination address. No policy, no traffic. Seems to be so basic that Keith the author left it out. Staying with the diagram in the recipe, yes, you communicate with the other LAN using the 'fake' addresses - how else?

If you use In the remote location you address So, by using VIPs on both sides, you drop using the original address space Configuring the local DNS will help your users a lot to cope with this. Attached Image s. So, what the VIPs are doing is translate a I understand the concept. But obviously, before that, there should have happened another translation from I believe, there has to be another set of VIPs for outbound traffic from internal lan to tunnel.

How else would the "source" Fortigate know that it should "snag" traffic, that is directed to a FortiGate v5. This article provides an example of the configuration of a dialup IPsec VPN with Split Tunneling to allow remote clients to securely access the resources of the internal protected network located behind FortiGate and at the same time, browse Internet directly from their local gateway.

For this reason, all of its traffic even Internet traffic has to be forwarded inside the IPsec tunnel to FortiGate, inspected by the respective firewall policies, forwarded to Internet and then back to the client through FortiGate.

As expected, this will introduce some amount of latency in Internet Browsing for a remote VPN client that has to access Internet and at the same time the protected network behind FortiGate.

The solution is to use Split Tunneling. This will allow the remote clients to access Internet considerably faster, as Internet traffic will be directly forwarded out their local gateway. Of course, this is a valid solution, only if inspection of Internet traffic that the clients initiate is not desired or imposed by corporate security policies.
