Default configuration for traffic that cannot be load balanced
The default configure load-balance flow-rule command contains the recommended default flow rules that control how the FortiGate-6000 handles traffic types that cannot be load balanced. All of the default flow rules identify the traffic type using the options available in the command and direct matching traffic to the primary (or master) FPC (action set to forward and forward-slot set to master). The default flow rules also include a comment that identifies the traffic type. Most of the flow rules in the default configuration are enabled and are intended to send common traffic types that cannot be load balanced to the primary FPC.
The default configuration also includes disabled flow rules for Kerberos and PPTP traffic. Normally, you would only need to enable these flow rules if you know that your FortGate will be handling these types of traffic.
The CLI syntax below was created with the show full configuration command.
