Step-by-Step Guide to Configuring SD-WAN in FortiGate Firewalls

Step-by-Step Guide to Setting up SD-WAN in FortiGate Firewalls and Configuring in the Panel

1. Log in to the FortiGate firewall web-based interface.
2. Go to Router > Software-Defined WAN (SD-WAN).
3. Click Create New under SD-WAN rules.
4. Choose Interface(s) you want to use for SD-WAN, and click Join.
5. Configure SD-WAN Rule:

• Set Source to all or specific network (depends on your requirements).
• Set Destination Address to any or specific IP address(es) (depends on your requirements).
• Set Services to allow specific or all services.
• Set Protocol as required (TCP, UDP, etc.).

1. Under Performance SLA section, configure performance metrics:

• Latency: Set the latency threshold in milliseconds.
• Jitter: Set the jitter threshold in milliseconds.
• Packet Loss: Set the packet loss threshold in percentage.

1. Click Save when finished configuring the rule.
2. Go back to Router > Software-Defined WAN (SD-WAN).
3. Configure Interface priorities by clicking Edit under Actions > Custom Setup for each selected Interface.

• Set Priority Percentage as per your requirement (lower value denotes higher priority).

1. Configure link health monitoring settings:
   • Enable/Disable Ping Server.
   • Modify server FQDN/IP address if needed.
   • Choose preference – Monitor Delay or Jitter – depending on your requirements.

11.Validation:
– Check the Status of interface(s) in SD-WAN dashboard.
– Following successful SD-WAN configurations, test traffic prioritization for different services by simulating network usage scenarios.

12. Monitor and manage SD-WAN performance using either FortiView or FortiAnalyzer tools for comprehensive insights.

You have now successfully set up SD-WAN using FortiGate Firewalls and configured it within the panel.
