At the moment I am receiving such logs from pretty much all the interfaces but the WAN interfaces which seems very odd as basicly as soon as you connect a device to Internet you would see scanning traffic. If the monitored interface status goes down or the ping server is not reachable, the default Configuring a FortiGate interface to act as an 802. Spanning tree. Therefore, this rule will try OL_MPLS_DC1 first (if currently within SLA) should the native ul_inet interface be in a brownout state, and then OL_MPLS_DC2 , but only if both ul_inet and OL_MPLS_DC1 are still out of SLA. g. Notice. It doesn't and the warning still trips. x, v7. In FortiGate, the route preference will be first policy route and then SD-WAN routes. set email-subject "interface" next. You should log as much information as possible when you first configure FortiOS. Probably I'm forgetting some steps or doing something wrong.
