Description This article describes the case of FortiAnalyzer connectivity with FortiGate using SD-WAN.
Scope FortiGate v6.X and v7.X.
Solution

Depending on how the FortiAnalyzer is connected to the FortiGate, a change may be required for the FortiGate to use the correct interface in the SD-WAN Zone.
By default, the FortiGate would do a regular route lookup when trying to access a resource and would not pay attention to SD-WAN rules or Policy Routes.
More details on this general behavior can be seen here: Technical Tip: Use SD-WAN for local out traffic or Management traffic (DNS, NTP, sflow,netflow, LDAP... 

If the FortiAnalyzer traffic needs to be steered with a rule, the following option should be set:

  1. Use the CLI and type in 'config log fortianalyzer setting'
  2. Use the following option: 'set interface-select-method SDWAN'.

  1. Test the connectivity:

  2. If only one specific interface should be used, it's possible to use 'set interface-select-method specify' instead.

     

    set interface-select-method specify
    set interface "ISP-1"
