FortiGate 60F Setup Guide with SD-WAN for Multiple WAN Connections This guide will help you configure your FortiGate 60F with the following features: Introduction to SD-WAN Three WAN Connections : Fiber (Primary), 5G, and Starlink SD-WAN Configuration : For load balancing and redundancy Three VLANs : Home, Guest, and IoT Firewall Rules : Optimized for streaming and gaming Traffic Prioritization : Using Quality of Service (QoS) Prerequisites FortiGate 60F : Ensure your FortiGate device is powered on and connected to your network. Access to FortiGate Management Interface : Use a web browser to access the FortiGate interface at https:// . WAN Connections : Have your Fiber, 5G, and Starlink connections physically connected to the FortiGate. Basic Network Knowledge : Familiarity with network configurations and terms. Step-by-Step Setup Step 1: Access FortiGate Management Interface Open a web browser and navigate to the FortiGate's IP address. Log in using your admin credentials. Default Username : admin Default Password : (Leave blank initially; change immediately for security) Step 2: Configure WAN Interfaces Navigate to Network > Interfaces to configure your WAN connections. Configure Fiber Connection (Primary) Interface Name : WAN_Fiber Physical Interface : e.g., port2 Role : WAN Addressing Mode : Configure according to your ISP (e.g., DHCP, Static, PPPoE) Distance : 5 (Lower distance gives higher priority in routing) Configure 5G Connection Interface Name : WAN_5G Physical Interface : e.g., port3 Role : WAN Addressing Mode : Configure according to your ISP Distance : 10 Configure Starlink Connection Interface Name : WAN_Starlink Physical Interface : e.g., port4 Role : WAN Addressing Mode : Configure according to your ISP Distance : 15 Step 3: Configure SD-WAN Navigate to Network > SD-WAN to set up load balancing and failover. Add Member Interfaces Click Create New to add WAN interfaces to SD-WAN. Add WAN_Fiber Interface : WAN_Fiber Weight : 0 Priority : 1 Add WAN_5G Interface : WAN_5G Weight : 0 Priority : 2 Add WAN_Starlink Interface : WAN_Starlink Weight : 0 Priority : 3 Configure SD-WAN Rules Go to the SD-WAN Rules tab. Click Create New . Name : Default_Rule Incoming Interfaces : VLAN_Home , VLAN_Guest , VLAN_IoT Source : All Destination : All Service : All Outgoing Interfaces : Best Quality (SLA) or Manual (choose preferred interfaces) Set Interface Preference Preferred Interfaces : WAN_Fiber , WAN_5G , WAN_Starlink Load Balancing Algorithm : Manual Step 4: Configure VLANs Navigate to Network > Interfaces to set up VLANs. Home VLAN Interface Name : VLAN_Home VLAN ID : 10 Interface : Physical interface connected to your switch (e.g., port1 ) IP/Netmask : 192.168.10.1/24 Guest VLAN Interface Name : VLAN_Guest VLAN ID : 20 Interface : port1 IP/Netmask : 192.168.20.1/24 IoT VLAN Interface Name : VLAN_IoT VLAN ID : 30 Interface : port1 IP/Netmask : 192.168.30.1/24 Step 5: Configure DHCP for Each VLAN Navigate to Network > DHCP Servers . Home VLAN DHCP Interface : VLAN_Home IP Range : 192.168.10.2 to 192.168.10.100 Guest VLAN DHCP Interface : VLAN_Guest IP Range : 192.168.20.2 to 192.168.20.100 IoT VLAN DHCP Interface : VLAN_IoT IP Range : 192.168.30.2 to 192.168.30.100 Step 6: Configure Security Policies Navigate to Policy & Objects > Firewall Policy . Allow Traffic from VLANs to SD-WAN Home VLAN to Internet Name : Allow_Home_to_Internet Incoming Interface : VLAN_Home Outgoing Interface : SD-WAN Source : All Destination : All Service : All Action : Accept NAT : Enable Guest VLAN to Internet Name : Allow_Guest_to_Internet Incoming Interface : VLAN_Guest Outgoing Interface : SD-WAN Source : All Destination : All Service : All Action : Accept NAT : Enable IoT VLAN to Internet Name : Allow_IoT_to_Internet Incoming Interface : VLAN_IoT Outgoing Interface : SD-WAN Source : All Destination : All Service : All Action : Accept NAT : Enable Deny Inter-VLAN Traffic Name : Deny_InterVLAN Incoming Interface : VLAN_Home , VLAN_Guest , VLAN_IoT Outgoing Interface : VLAN_Home , VLAN_Guest , VLAN_IoT Source : All Destination : All Service : All Action : Deny Step 7: Configure Traffic Prioritization (QoS) Navigate to Policy & Objects > Traffic Shapers . Create Traffic Shapers Gaming Traffic Shaper Name : Priority_Gaming Type : Per Policy Priority : High Bandwidth : Set according to your requirements Streaming Traffic Shaper Name : Priority_Streaming Type : Per Policy Priority : Medium Bandwidth : Set according to your requirements Apply Traffic Shapers to Policies Edit the Allow_Home_to_Internet policy. Under Traffic Shaping , enable Apply Shaper Per Policy . Select the appropriate traffic shaper based on the service. Step 8: Configure SD-WAN Performance SLA (Optional) Navigate to Network > SD-WAN > Performance SLA . Create SLA Targets Click Create New . Name : SLA_Fiber Members : WAN_Fiber Latency , Jitter , Packet Loss : Set thresholds Protocol : Ping or HTTP Server : Reliable external IP (e.g., 8.8.8.8) Repeat for WAN_5G and WAN_Starlink if desired. Configure SD-WAN Rules with SLA Go back to SD-WAN Rules . Edit Default_Rule . Under SLA , select the SLA targets you created. Set the SLA Mode to Best Quality . Step 9: Test Configuration Connectivity : Verify that devices on each VLAN receive the correct IP addresses and can access the internet. Failover : Disconnect the Fiber connection to test if traffic fails over to 5G or Starlink. Load Balancing : Monitor traffic to see if load balancing is functioning as configured. QoS : Test streaming and gaming applications to ensure they receive priority bandwidth. Additional Tips Secure Access : Change the default admin password and enable HTTPS-only access under System > Settings . Regular Backups : Go to System > Maintenance > Backup & Restore to back up your configuration. Firmware Updates : Check System > Firmware for updates to keep your FortiGate secure and up-to-date. By following this guide, you should have a robust network setup that leverages SD-WAN to manage multiple WAN connections, provides separate VLANs for different device types, and prioritizes critical traffic like gaming and streaming. The Fiber connection is set as the primary link, ensuring the best performance under normal conditions, with 5G and Starlink as backups for redundancy.
