In Dual Gateway mode, how is external traffic handled?

In Dual Gateway mode, external traffic is routed through an external router, and modifications are made to ensure proper internal routing. This means that when traffic originates from outside the internal network, it must pass through the configured gateways that manage access and security controls. The external router plays a crucial role in modifying traffic so that it adheres to the internal routing requirements, which may include changes in IP addresses and transport protocols that ensure the data can be properly handled once it enters the internal network.

This process is essential in maintaining a secure and efficient flow of information, as it helps to segregate and control external requests while ensuring that they reach the correct destinations within the internal network. The modifications are crucial for various reasons, such as implementing NAT (Network Address Translation) or ensuring that only authorized traffic can access sensitive internal resources.

In contrast, the other options do not accurately reflect how Dual Gateway mode is designed to handle external traffic and its modifications necessary for secure routing. For instance, sending traffic directly to the internal network without modification would bypass vital security protocols. Restricting traffic to specific clients does not address the handling of external traffic and monitoring it for security purpose, while logging and monitoring are important for security best practices, they do not specifically pertain to the routing
