In FortiGate, what type of policies could impact the routing table aside from the default routes?

The type of policies that could impact the routing table in FortiGate are firewall policies. Firewall policies are crucial because they define how traffic is handled through the FortiGate unit. They determine whether traffic flows through a specific interface and can also influence the route taken based on the defined policies.

When traffic matches a firewall policy, it might be forwarded to a specific next hop, which can dynamically alter the routing table, especially in complex scenarios involving policy-based routing. This capability allows administrators to control not just security but also traffic flow within the network.

The other types of policies mentioned, such as content filtering, trust, and web filtering policies, focus more on the content of the traffic or its categorization rather than directly influencing the paths through which data packets travel in the network. They may enforce security or compliance but do not alter the routing itself within the FortiGate's routing table.
