FortiSASE supports two main routing design methods for Secure Private Access (SPA) when connecting to a FortiGate SD-WAN hub:

BGP per Overlay (Traditional/Default Method): In this configuration, a separate iBGP session is established over every individual IPsec overlay (tunnel) between the FortiSASE PoP and the hub. These sessions terminate on the tunnel interface IP addresses . To facilitate this, the hubs typically use the IPsec VPN mode-cfg feature to dynamically assign tunnel IP addresses to the SASE PoPs. For every LAN prefix, the system generates multiple BGP routes —one for each overlay—which increases the total number of routes advertised across the network.

BGP on Loopback (Modern Alternative): This newer design establishes only a single iBGP session between the spoke and the hub, regardless of how many physical or logical overlays (tunnels) connect them. The session is terminated on a loopback interface on both sides.

Key Advantages of BGP on Loopback:

Reduced Complexity: It significantly simplifies the BGP configuration because there are fewer neighbors to manage. 2

Improved Scalability: It greatly reduces the volume of routes advertised, as only a single BGP route is generated for each LAN prefix, making it the preferred choice for large-scale deployments.

Resiliency: The BGP session remains active as long as the loopback is reachable via any of the available overlays, meaning no BGP convergence is required if a single overlay fails.

FortiSASE Geofencing and Regional Compliance allow administrators to control where remote users connect based on their physical location, which is determined by the endpoint ' s public IP address. 3

Default Connection Behavior: By default, FortiSASE uses a " best-effort " geolocation logic to ensure the lowest latency for the user. If an administrator has not configured a specific regional compliance rule for a user ' s country or region, FortiClient will automatically attempt to connect to the closest available FortiSASE security PoP (Point of Presence) based on proximity. 4

Regional Compliance Rules: When an organization must enforce data residency or specific security routing requirements, they create Regional Compliance rules. According to the FortiSASE 25 Feature Administration Guide , these rules allow the administrator to override the default " closest PoP " behavior for specific countries.

Connectivity Options: Within a regional compliance rule, the administrator must specify the destination for the traffic. The system provides a choice between two distinct connection types: a FortiSASE Security PoP or an On-premises device (such as a FortiGate acting as a gateway). 5 The documentation specifies that a rule is designed to point to one of these types at a time to satisfy the compliance requirement for that specific region.

Connection Priority: While multiple connections can be managed in a priority table, the logic for Regional Compliance is focused on directing the user to the designated compliant entry point. Option D is incorrect because the connection order is determined by the Priority and custom fail-over connections table ; an administrator can manually adjust the sequence, so it is not " always " the security PoP first.

In FortiSASE, Zero Trust Network Access (ZTNA) tags—also known as security posture tags—are used to dynamically grant or deny access based on the real-time security state of an endpoint. This mechanism ensures that only devices meeting specific compliance requirements can access protected resources or the internet.

Endpoint Analysis: The Managed Endpoints exhibit shows that while Jumpbox only has the FortiSASE-Compliant tag, the Windows-AD endpoint has been assigned both FortiSASE-Compliant and FortiSASE-Non-Compliant tags. This indicates that a security posture check on the Windows-AD device has failed, triggering a rule that applies the non-compliant tag.

Policy Evaluation: The Secure Internet Access Policy table shows two custom policies. The first policy, named Non-compliant , uses the FortiSASE-Non-Compliant tag as its source and has the action set to Deny . The second policy, Web Traffic , allows access for FortiSASE-Compliant users.

Root Cause of Outage: Because FortiSASE (powered by FortiOS) processes security policies in a top-down sequence, the " Non-compliant " policy is evaluated first. Since Windows-AD matches the source criteria for this " Deny " policy, its traffic is blocked before it can reach the " Accept " policy.

Although the exhibit shows a warning icon for the FortiClient version on Windows-AD, the direct cause of the internet outage is the explicit Deny policy triggered by the change in the device ' s security posture (the application of the Non-Compliant tag).
