I´ve 2 fortigate 100c running in HA mode (cluster) and 2 1921 cisco routers connected to them to give Internet.
In the cluster config Router->Static->Setting-> is a Dead gateway detection zone. The cluster has wan 1 wan2 an local1 to lan.
Wan 1 is checking cisco router 1st
Wan 2 is checking internet is up
Wan2 is a backup line
2 days ago, our IPS crashed and although the cisco router 1st was up, was not internet connection and, ofcourse, the routes did not change to wan 2.
My question, how to check 1st router and internet bouth through wan1 and.. if a failuer change to wan2 ?
