Hi, I'm using 100EF FortiGate. from past few day its alerting on my email WAN1 Down and after few seconds it alerts WAN1 Up.
I'm running two ISPs. I haven't updated its firmware yet. WAN1 connection is via Fiber media converter then a Router and it further in the FortiGate. here is the error. Do let me know how to avoid this hitch.
"type="event" subtype="system" level="critical" vd="root" logdesc="Routing information changed" name="google" interface="wan1" status="down" msg="Static route on interface wan1 may be removed by health-check google. Route: (192.168.30.119->126.96.36.199 ping-down) (192.168.30.119->188.8.131.52 ping-down)"
Thank you for posting to the Fortinet Community Forum.
From your description I can understand that you are getting multiple alert email stating that your wan1 is down
As per the logs the alert mail is regarding the performance sla which you must have configured in SDWAN. It is not stating the information regarding the interface is being down but the link from wan1 is down due to which it is removing the default route from wan1 from the routing table From the logs I could see that you have configured source IP
Can you check by removing the source IP config system sdwan config members edit 1 unset source
Also consult with your ISP why the link is being down and 184.108.40.206 is unreachable.
