we've had a problem lately that all VPN tunnels have been disconnected.
In FortiAnalyzer in the Event Logs for System I could see, that at those times the Static Route for the WAN Status Check has changed.
Static Route is removed. Route xxxx -> xxxx ping-down.
and then 1 minute later:
Static Route is added. Route xxxx -> xxxx ping-up
I assume that this is/was a provider problem.
Do you see the same or maybe the firewall can be guilty.
If anyone has any suggestions for me, please come here. Thanks for every advice.
We have a FortiGate 500D with FortiOS 5.4.6 installed.
