I did a simple exercise where I connected the two PCs to the physical FortiGate (to port1 and port2). Then I created a rule where I set the incoming traffic to port1 and outgoing traffic to port2 (with all other parameters set to 'all'). I also created another rule to permit the reverse traffic. However, all traffic is being denied due to the implicit deny rule. Does anyone have a suggestion regarding this configuration? I can ping the FortiGate from the PCs. The FortiGate is not registered yet (I did the same configuration in VMware Workstation with the FortiGate running on a VM, and it worked).
Solved! Go to Solution.
Dear all,
I did reset to the factory configuration, and didn't have any problems after. Thank you very much for your support!
Dear @Giovanna ,
Please run the debug command to check the traffic flow and the firewall policy that is matching:
# diagnose debug disable
# diagnose debug flow filter addr <Source_IP> <Destination_IP> and
# diagnose debug flow show function-name enable
# diag debug flow show iprope enable
# diagnose debug console timestamp enable
# diagnose debug flow trace start 1000
# diagnose debug enable
Best regards,
Erlin
Thank you! Debug didn't show any issues, looks like fortigate takes time to load the configuaration modifications, do you mabye know why this happends? It takes more then 1 hour
Dear @Giovanna,
Thank you for the reply!
Did you notice the traffic that is flowing into FGT from Sniffer commands?
# diag sniffer packet any "host <Source_IP> and host <Destination_Ip>" 4 0 l
Best regards,
Erlin

Hi @Giovanna ,
You need to tell us the details about your traffic:
Ping or HTTP or something else?
Source IP / Destination IP?
The outputs of the debug flow.
And/or the outputs of the sniffer packets capture.
Hi Giovana
Jerry and Salija are right, if you share "diag debug flow" output it will help us to help you.
