FortiGate Troubleshooting - Debug Flow with Examples

Debug flow will help you troubleshoot the logic process the FortiGate takes when forwarding traffic. We will go over some specifics on reading debug flow: Traffic direction Interfaces Routing Policy Matching Trace ID Session matching "No matching IPsec selector, drop" message "Allowed by Policy" message "reverse path check fail, drop" message "Denied by forward policy check (policy 0)" message Debug Flow Command Review: diag debug flow filter #view the current filter diag debug flow filter clear #clear the debug flow filter diag debug flow filter proto 1 #filter for protocol 1 diag debug flow filter addr x.x.x.x diag debug console timestamp enable #enable timestamp in outputs diag debug flow trace start x #how many packets to trace/debug diag debug enable #enable the debug diag debug disable #disable the debug diag debug reset #reset all debug parameters (includes debug flow filter clear) 0:00 Overview 0:38 Debug Flow Filter 2:07 Example #1 - working example 4:45 Example #2 - non-working example 6:49 Example #3 - another non-working example
