Troubleshooting Tip: Routes are advertised to FortiSASE but FortiSASE is not adding the routes to routing table

Issue: A user complains that while the Hub is advertising the '10.252.x.x/24' network correctly, it is not showing in FortiSASE.

Solution: Review the Network Restriction page in the Network Configuration. The 10.252.0.0/24 network is one of the reserved networks for FortiSASE usage and should not be advertised by the customer and will be blocked by the FortiSASE using a route map, so the route will not show in the routing table.

Go to Network -> Secure Private access. As shown below, the Network restrictions will appear on the right side of the page.
