In most units, this is done either by a Serial cable or an RJ-45 to Serial cable. There are some units that use a USB cable and FortiExplorer to connect to the console port. The FortiExplorer wizard enables easy setup and configuration coupled with easy-to-follow instructions. FortiExplorer runs on popular mobile devices like Android and iOS. Using FortiExplorer is as simple as starting the application and connecting to the appropriate USB port on the FortiGate. By using FortiExplorer, you can be up and running and protected in minutes.High performance UTM — firewall, VPN, IPS, application control, web filtering, antivirus, antispam, DLP and more Hardware Unit, 24x7 Comprehensive Support, Advanced Hardware Replacement (NBD), Firmware and General Upgrades, UTP Services Bundle (IPS, AV, Botnet IP/Domain, Mobile Malware, FortiGate Cloud Sandbox including Virus Outbreak and Content Disarm & Reconstruct, Application Control, Web & Video Filtering and Antispam Service) plus term of contract FGT_30E-v6-buildxxxx-FORTINET.out – Normal FortiGate build, no built in wireless hardware at all. Serial number starts with FGT30E The FortiGate supports external 3G/4G modems that allow additional or redundant WAN connectivity for maximum reliability. The FortiGate can also operate as a wireless access point controller to further extend wireless capabilities.

One of the really cool features of the FortiGate 30E is the Traffic Shaper. In essence, you can assign a high priority to VoIP traffic and a minimum amount of bandwidth to ensure you clients can hear you clearly and easily. There is a wireless version for the MI and MN versions as well. Each one of these models are different hardware configurations.Common causes of getting 100Mb/s connection rather than 100Mb/s are faulty Ethernet cabling or perhaps negotiation/ speed settings between the Fortigate and the modem/ internet device. Unified Threat Protection (UTP) (IPS, Advanced Malware Protection, Application Control, Web & Video Filtering, Antispam Service, and FortiCare Premium)

The FortiGate/FortiWiFi 30E offers beyond the industry’s best firewall with the latest in Advanced Threat Protection including Sandboxing and anti-bot protection, Feature Select Options for simplifying configurations and deployments, and Contextual Visibility for enhanced reporting and management. Your "diagnose hardware deviceinfo nic wan" shows that too- the "Speed 100" agrees with what the AMBER speed LED indication is showing you. Ideally, you probably do want the D-Link to act as a pure modem- but you would need to reconfigure it (if that is even possible?) and let the Fortigate act as the only router on your network. The Fortigate may then need to run PPPoE (for example) depending on how the ISP manages connections. Advanced Threat Protection (IPS, Advanced Malware Protection Service, Application Control, and FortiCare Premium)In newer versions of the BIOS, expect some changes to the behavior of the maintainer account. These changes will include: Maximum firewall throughput is 950Mb/s and if you use full threat protection (which you should) maximum throughput is about 150Mb/s (depending on traffic type and mix). But, there is certainly nothing (even with the 30E) that will prevent you getting that speed reliably if you have it correctly configured. It will be a config issue and certainly not a bug or Fortinet defect. These basic configs work well on Fortigates and are well validated and tested. But it may take time to work through it. Once you know where to look, the visibility into network traffic is amazing. FortiView provides information on traffic in and out of LAN/DMZ and traffic from the WAN interface. This gives you a good overview of the bandwidth used by device or by application, the category of the traffic, and the risk associated with the traffic. Plus, you can also look under Log and Report for real-time traffic, which policy is being used, application control and web filter triggered events. Once logged into the FortiGate with the maintainer account (as described below), if the FortiGate is running FortiOS 6.0.3 or later, enter the execute factoryreset command to return the FortiGate to its default configuration.
