Connect a Fortigate device behind a static 1:1 NAT to the Internet to a Google Cloud Platform (GCP) VPN gateway. For example, you might have an intranet.example.com web server located at Site A. An attacker can leverage this fingerprint to craft exploits for a specific system or configuration. Configure the local tunnel on the Site A Firebox to use 1-to-1 NAT so that traffic from the Site A trusted network appears to come from the 192.168.100.0/24 range when it goes through the VPN to Site B. These settings do not affect VPNtraffic. By clicking Accept, you consent to the use of cookies. Easy to understand. You do not have to define any parameters in the Network >NAT settings. For best results, consider creating a DoS protection policy that includes all of FortiWebs DoS defense mechanisms, and block traffic that appears to originate from another country, but could actually be anonymized by VPN or Tor. DoS can also be used as a diversion tactic while a true exploit is being perpetrated. This causes a TCP flow to repeatedly enter a RTO state and significantly reduces TCP throughput.
