Which static route is automatically added to the client's routing table when tunnel mode is activated?

When tunnel mode is activated in a Fortinet environment, specifically relating to SSL VPN configurations, a static route is automatically added to direct traffic to the appropriate destination subnet for the clients connecting via the tunnel. This route corresponds to the destination subnet defined in the configuration of the VPN, ensuring that traffic destined for the internal servers flows correctly through the established VPN tunnel.

In this context, the address object representing the Internal_Servers identifies the specific subnet that hosts the resources the client will access while connected through the VPN. The routing table update upon establishing the tunnel allows for seamless connectivity to these servers, directing IP traffic appropriately.

The choice regarding a route to the destination subnet configured in the tunnel mode widget implies that the specific settings for the VPN are instrumental in determining routing paths, as they incorporate the necessary parameters for client access to the intended network resources.

While the other options may have relevance in other contexts (like default routes or global SSL VPN settings), the clear connection between tunnel mode activation and the establishment of a route to a destination subnet matching the defined address object for Internal_Servers makes this answer the most accurate interpretation of the automatic routing behavior in operation.
