SD-WAN vs Dual Internet Connection

[badboy23]

Hi All,

May I know the different between these two? I have two internet line and would like to form load sharing / resilience link on Fortigate 300D, thank you!

Quote from FortiOS handbook for FortiOS 6.0

Dual Internet connections Dual internet connections, also referred to as dual WAN or redundant Internet connections, refers to using two FortiGate interfaces to connect to the Internet. You can use dual Internet connections in several ways: - Redundant interfaces: If one interface goes down, the second interface automatically becomes the main Internet connection. - Load sharing: This ensures better throughput. - Use a combination of redundancy and load sharing. Redundant interfaces

Quote from Fortigate Cookbook
