To resolve internal hostnames using internal DNS servers for remotely connected endpoints, the following two components must be configured on FortiSASE:

Split DNS Rules:

Split DNS allows the configuration of specific DNS queries to be directed to internal DNS servers instead of public DNS servers.

This ensures that internal hostnames are resolved using the organization's internal DNS infrastructure, maintaining privacy and accuracy for internal network resources.

Split Tunneling Destinations:

Split tunneling allows specific traffic (such as DNS queries for internal domains) to be routed through the VPN tunnel while other traffic is sent directly to the internet.

By configuring split tunneling destinations, you can ensure that DNS queries for internal hostnames are directed through the VPN to the internal DNS servers.

FortiOS 7.2 Administration Guide: Provides details on configuring split DNS and split tunneling for VPN clients.

FortiSASE 23.2 Documentation: Explains the implementation and configuration of split DNS and split tunneling for securely resolving internal hostnames.

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.

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.

The Secure Web Gateway (SWG) policy is used to control traffic between the FortiClient endpoint and FortiSASE for secure internet access. SWG provides comprehensive web security by enforcing policies that manage and monitor user access to the internet.

Secure Web Gateway (SWG) Policy:

SWG policies are designed to protect users from web-based threats and enforce acceptable use policies.

These policies control and monitor user traffic to and from the internet, ensuring that security protocols are followed.

Traffic Control:

The SWG policy intercepts all web traffic, inspects it, and applies security rules before allowing or blocking access.

This policy type is crucial for providing secure internet access to users connecting through FortiSASE.

FortiOS 7.2 Administration Guide: Details on configuring and managing SWG policies.

FortiSASE 23.2 Documentation: Explains the role of SWG in securing internet access for endpoints.

The unusually high number of unknown applications by category in the daily report for application usage can be attributed to the following reasons:

Certificate Inspection is not being used to scan application traffic:

Without certificate inspection, encrypted traffic cannot be adequately analyzed, leading to a higher number of unknown applications.

Certificate inspection allows the FortiSASE to decrypt and inspect HTTPS traffic, identifying applications correctly.

Deep Inspection is not being used to scan traffic:

Deep inspection goes beyond basic traffic analysis, performing thorough examination of packet contents to identify applications accurately.

If deep inspection is not enabled, many applications may go unrecognized and categorized as unknown.

FortiOS 7.2 Administration Guide: Details on certificate inspection and deep inspection configurations.

FortiSASE 23.2 Documentation: Explains the importance of deep inspection and certificate inspection in accurate application identification.
