The VPN tunnel between the FortiSASE spoke and the FortiGate hub is not establishing due to the configuration of mode config, which is not supported by FortiSASE spoke devices. Mode config is used to assign IP addresses to VPN clients dynamically, but this feature is not applicable to FortiSASE spokes.

Mode Config in IPsec:

The configuration snippet shows that mode config is enabled in the IPsec phase 1 settings.

Mode config is typically used for VPN clients to dynamically receive an IP address from the VPN server, but it is not suitable for site-to-site VPN configurations involving FortiSASE spokes.

Configuration Adjustment:

To establish the VPN tunnel, you need to disable mode config in the IPsec phase 1 settings.

This adjustment will allow the FortiSASE spoke to properly establish the VPN tunnel with the FortiGate hub.

Steps to Disable Mode Config:

Access the VPN configuration on the FortiSASE spoke.

Edit the IPsec phase 1 settings to disable mode config.

Ensure other settings such as pre-shared key, remote gateway, and BGP configurations are correct and consistent with the FortiGate hub.

To block all video and audio application traffic while granting access to videos from CNN, you need to configure an application override action in the Application Control with Inline-CASB. Here is the step-by-step detailed explanation:

Application Control Configuration:

Application Control is used to identify and manage application traffic based on predefined or custom application signatures.

Inline-CASB (Cloud Access Security Broker) extends these capabilities by allowing more granular control over cloud applications.

Blocking Video and Audio Applications:

To block all video and audio application traffic, you can create a policy within Application Control to deny all categories related to video and audio streaming.

Granting Access to Specific Videos (CNN):

To allow access to videos from CNN specifically, you must create an override rule within the same Application Control profile.

The override action "Exempt" ensures that traffic to specified URLs (such as those from CNN) is not subjected to the blocking rules set for other video and audio traffic.

Configuration Steps:

Navigate to the Application Control profile in the FortiSASE interface.

Set the application categories related to video and audio streaming to "Block."

Add a new override entry for CNN video traffic and set the action to "Exempt."

According to the NSE7 SASE Enterprise Guide (Pages 64 & 153), FortiSASE utilizes an intelligent engine to manage connectivity to private resources through various selection methods:

Hub Health and Priority: FortiSASE incorporates a built-in SD-WAN engine for intelligent routing selection among established IPsec links. The health check IP address periodically receives performance metrics, including jitter, latency, and packet loss, for each service connection. In this mode, FortiSASE evaluates the available hubs and selects the one with the highest priority (the most preferred value) within each POP, provided that the hub meets the defined service-level agreement (SLA) requirements. For this configuration to function correctly, both FortiSASE and the SPA hub must use the same Autonomous System Number (ASN).

BGP Multiple Exit Discriminator (MED): This method leverages the standard BGP MED attribute, which allows an autonomous system to signal its preferred entry point to a peer. FortiSASE learns the MED values advertised by the configured hubs. The architecture is designed so that the lower the MED value, the more preferred the path is to the receiving router. Consistent with the "Zero Trust" and "Secure Access" principles, even when using BGP MED, the selection is gated by the health engine; therefore, the hub is only selected if it also satisfies the configured SLA thresholds.

While SLA thresholds can be configured, the primary logic for hub selection focuses on how priority and dynamic routing attributes (like MED) interact with the real-time health of the tunnel.

If the daily summary report generated by FortiSASE contains very little data, one possible explanation is that the "Log allowed traffic" setting is configured to log only "Security Events" for all policies. This configuration limits the amount of data logged, as it only includes security events and excludes normal allowed traffic.

Log Allowed Traffic Setting:

The "Log allowed traffic" setting determines which types of traffic are logged.

When set to "Security Events," only traffic that triggers a security event (such as a threat detection or policy violation) is logged.

Impact on Report Data:

If the log setting excludes regular allowed traffic, the amount of data captured and reported is significantly reduced.

This results in reports with minimal data, as only security-related events are included.

Integrating FortiManager with FortiSASE allows for central management of configuration objects like addresses and 5 security 6 profiles. For this integration to function correctly, the following key prerequisites must be met:

Same FortiCloud Account: A fundamental requirement for the integration is that both 10 the FortiSASE instance and the FortiManager (whether physical, VM, or Cloud) must be registered under the same FortiCloud (FortiCare) account . This common identity allows the platforms to securely discover and authorize each other for synchronization.

Supported Firmware Version: The FortiManager must run a firmware version that is compatible with the FortiSASE release. According to the FortiSASE 25 Enterprise Administrator Study Guide , FortiManager version 7.4.4 or later is generally required to support the specific API connectors and object synchronization logic used by current FortiSASE environments. Using an unsupported version may result in synchronization failures or missing configuration features.

Management Logic: Once these prerequisites are met, the administrator can enable " Central Management " in the FortiSASE portal. This creates a one-way synchronization where FortiManager acts as the source of truth for objects like Security Profile Groups, ensuring consistent security posture across both the SASE cloud and on-premises FortiGates.

In a FortiSASE environment, the ability of a remote user to establish a VPN tunnel is governed not only by their credentials and firewall policies but also by geographic access controls .

Geofencing Mechanism: FortiSASE includes a Geofencing feature (found under Configuration > Restrictions or Configuration > Geofencing in newer versions) that allows administrators to restrict or allow access to SASE services based on the geographic location of the endpoint ' s public IP address.

Connection Failure vs. SSO Success: The scenario describes a situation where users can successfully authenticate via SSO to reach third-party SaaS apps like Office 365 (O365) or Salesforce (SFDC) but cannot connect to the SASE VPN. This occurs because the SSO authentication is handled directly by the Identity Provider (IdP) (e.g., Microsoft Entra ID), which may not have the same geographic restrictions. However, when the FortiClient attempts to establish the tunnel to the FortiSASE Point of Presence (PoP), the SASE gateway checks the Geofencing list . If the country the user is visiting is on the Deny list (or not on the Allow list), the connection is dropped at the " local-in " policy level on the SASE backend, preventing the tunnel from forming.

Verification and Resolution: To resolve this, the administrator must verify the Geofencing settings and ensure that the countries where the traveling users are located are permitted to connect. If the feature is enabled with a " Deny " list, the specific country must be removed from that list; if it uses an " Allow " list, the country must be added.

Analysis of Other Options:

Option A: Firewall policies govern traffic after the tunnel is established; they cannot resolve a failure to connect the tunnel itself.

Option B: Restarting the device is a general troubleshooting step but will not bypass a server-side geographic block.

Option D: While keeping clients updated is a best practice, the issue described (specific to overseas travel while other functions work) points to a configuration restriction rather than a software bug.

To meet the requirement of inspecting all endpoint internet traffic on FortiSASE while excluding Google Maps traffic from the FortiSASE VPN tunnel and redirecting it to the endpoint ' s physical interface, you should configure split tunneling. Split tunneling allows specific traffic to bypass the VPN tunnel and be routed directly through the endpoint ' s local interface.

Split Tunneling Configuration:

Split tunneling enables selective traffic to be routed outside the VPN tunnel.

By configuring the Google Maps Fully Qualified Domain Name (FQDN) as a split tunneling destination, you ensure that traffic to Google Maps bypasses the VPN tunnel and uses the endpoint ' s local interface instead.

Implementation Steps:

Access the FortiSASE endpoint profile configuration.

Add the Google Maps FQDN to the split tunneling destinations list.

This configuration directs traffic intended for Google Maps to bypass the VPN tunnel and be routed directly through the endpoint ' s physical network interface.

During FortiSASE provisioning, the FortiSASE administrator needs to configure at least one security point of presence (PoP). A single PoP is sufficient to get started with FortiSASE, providing the necessary security services and connectivity for users.

Security Point of Presence (PoP):

A PoP is a strategically located data center that provides security services such as secure web gateway, firewall, and VPN termination.

Configuring at least one PoP ensures that users can connect to FortiSASE and benefit from its security features.

Scalability:

While only one PoP is required to start, additional PoPs can be added as needed to enhance redundancy, load balancing, and performance.

The Digital Experience Monitor (DEM) feature in FortiSASE is a specialized monitoring tool integrated into the SASE cloud to ensure optimal application performance and user satisfaction. 2

Purpose and Visibility : DEM is designed to provide end-to-end network visibility by monitoring the health and performance of the connections between the global FortiSASE security Points of Presence (PoPs) and specific SaaS applications (such as Microsoft 365, WebEx, or Dropbox).

Performance Metrics : It identifies and helps troubleshoot issues related to latency, jitter, and packet loss . By leveraging vantage points within the SASE infrastructure, administrators can determine if a performance bottleneck resides within the local network, the SASE backbone, or the SaaS provider ' s environment.

Integration : This feature is often powered by FortiMonitor , allowing for synthetic transaction monitoring (STM) to simulate user interactions and proactively spot performance issues before they impact the hybrid workforce.

Operational Efficiency : By providing comprehensive insights across users and PoPs, DEM reduces the time required to resolve " slowness " complaints, which are common in remote work scenarios.

Comparison of Other Features:

Option A : While FortiSASE monitors PoP health, DEM ' s primary value is the end-to-end path to the application.

Option B : Compliance checks are a function of Endpoint Profiles and ZTNA tagging rules, not the monitoring dashboard.

Option D : Vulnerability management is handled by the Vulnerability Scan feature within the managed FortiClient settings.

When providing Secure Private Access (SPA) to external contractors who may not be using managed corporate devices, FortiSASE offers specific methods to ensure security while maintaining ease of use.

Bookmark Portal (Clientless Access): For web-based resources like a web server, the recommended and most efficient method for contractors is to use the ZTNA portal (bookmark portal) . This allows for clientless access , meaning the contractor does not need to install the FortiClient agent or any specific software on their personal machine.

Workflow: The administrator publishes the web server URL as a bookmark within the FortiSASE portal. Contractors simply log into the secure SASE web portal via their browser, authenticate, and click the bookmark to access the internal server.

Security Benefits: This method leverages the FortiSASE ZTNA access proxy to mediate the connection. It ensures that the contractor is authenticated and that the traffic is inspected without exposing the internal network directly to the contractor ' s device.

Analysis of Incorrect Options:

Option A: TCP forwarding rules require the FortiClient agent to be installed and managed on the endpoint. Contractors often use unmanaged devices where installing agents is restricted or undesirable.

Option C: Updating a PAC (Proxy Auto-Configuration) file is part of a Secure Web Gateway (SWG) deployment for internet access, not for routing traffic to private internal web servers via an SPA hub. 1

Option D: Manually updating DNS records on a contractor ' s endpoint is an unscalable, insecure, and administratively heavy task that does not provide the session-level security required by ZTNA.
