    Benefits and limitations of the DNAT mode

    Benefits and limitations of the DNAT mode

    Key benefits

    • Client IP Preservation: Back-end servers see the original client IP address, as no source NAT is applied. This is ideal for environments where maintaining accurate client identity is important for logging, auditing, or security policies.

    • Back-End Server IP Protection: Clients interact only with the Virtual IP (VIP) configured on FortiADC, not the real IP addresses of the back-end servers. This setup prevents the exposure of internal server IPs to the Internet, effectively hiding the actual server infrastructure and reducing the attack surface.

    • Simpler Server Configuration: Unlike in Direct Routing (DR) mode, back-end servers do not need to be configured with the VIP. They operate using their own IP addresses, making deployment and maintenance simpler.
