Hello again,

I found this solution. Can you tell me if it helps, please?

It seems like you are experiencing an issue with split tunneling where internet traffic is incorrectly routed through the VPN tunnel. Here are some steps to troubleshoot and potentially resolve the issue:

1. Verify Split Tunnel Configuration: Ensure that the split tunnel is correctly configured on the FortiGate. Check the VPN settings to confirm that only specific subnets are included in the tunnel, and internet traffic should be excluded.
   
   
2. Check Route Configuration: Verify the route configuration on the FortiGate. Ensure that the default route is not being pushed to the VPN interface. This can be checked in the VPN settings under the phase 2 configuration.
   
   
3. Compare with Working Configuration: Since you mentioned that connecting to another FortiGate running version 7.4.8 works correctly, compare the configuration of both FortiGates. Look for differences in the VPN and routing settings.
   
   
4. Review FortiClient Configuration: - Ensure that the FortiClient is configured to respect the split tunnel settings. Check the FortiClient logs for any discrepancies.
   
   
5. Upgrade to Latest Version: If the issue persists, consider upgrading to FortiGate version 7.4.8, as it may contain fixes not documented in the release notes.
   
   
6. Consult Fortinet Support: If none of the above steps resolve the issue, it may be a bug specific to version 7.4.7. Contact Fortinet Support for further assistance and to report the potential bug.

By following these steps, you should be able to identify and resolve the issue with split tunneling.
