config firewall policy edit 0 set diffservcode-forward 001001 end diffservcode-rev. When viewing the FortiGate logs, you may find an entry indicating policyid="0". N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
- Is the ARP resolution correct for the targeted next-hop? offloading must be disabled. The valid range is 000000-111111. Syntax: The FortiGate system memory and local disk can also be configured to store logs, so it is also considered a log device. i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
A client workstation is connected to FortiGate port2. C 192.168.182.0/23 is directly connected, port12.1 - Verify that all appropriate services are opened on the interface that is being access (telnet, http...)2.2 - If the interface is accessed via another port of the FortiGate, a firewall policy must exist to allow this traffic Take a sniffer trace as per the following examples when running a constant ping (or TCP connection) from PC1 to PC2. From what I can tell that means there is no policy matching the traffic. trace or a debug flow as the traffic will not be seen with this
procedure. Assuming the tunnel is good, the next thing I would do is a flow debug. Please refer to the related article given
For using the sniffer and debug flow with NP2 ports, NP2

If not, proceed with a debug flow as follows: diag debug flow trace start 100 <== this will display 100 packets for this flow To stop all other debug, type "diag debug flow trace stop". 2 mensajes • Página 1 de 1 Reports show the recorded activity in a more readable format.
Troubleshooting Tip : First steps to troubleshoot connectivity problems to or through a FortiGate with sniffer, debug flow, session list, routing table
- Is the traffic exiting the FortiGate to the destination?FGT# diagnose sniffer packet any "host and host " 4FGT# diagnose sniffer packet any "(host and host ) and icmp" 4 Including the ARP protocol in the filter may be useful to troubleshoot a failure in the ARP resolution (for instance PC2 may be down and not responding to the FortiGate ARP requests)FGT# diagnose sniffer packet any "host and host or arp" 4 With verbosity 4 above, the sniffer trace will display the port names where traffic ingresses/egresses. Examples of results that may be obtained from a debug flow :3.1 - The following is an example of debug flow output for traffic that has got id=20085 trace_id=319 func=resolve_ip_tuple_fast line=2825 msg="vd-root received a packet(proto=6, 192.168.129.136:2854->192.168.96.153:1863) from port3." diag debug reset diag debug flow filter daddr diag debug flow show console enable diag debug flow show function-name enable diag debug flow trace start 1000 diag debug enable id=13 trace_id=4412 func=fw_forward_handler line=534 msg=”Denied by forward policy check” ### When you finish testing, disable debugging and clear the … The value is 6 bits binary. further below.If the FortiGate is running in NAT mode, verify that all desired routes are in the routing table : local subnets, default routes, specific static routes, dynamic routing protocol.The Fortigate will drop packets in case of RPF check failure (see related article at the end of this page Details about RPF (Reverse Path Forwarding), also called Anti Spoofing, on FortiOS
For example:2008-10-06 00:13:49 log_id=0022013001 type=traffic subtype=violation pri=warning vd=root SN=179089 duration=0 user=N/A group=N/A rule=0 Any firewall policy that is automatically added by the FortiGate unit has a policy ID number of 0.The following are the most commonly created by the FortiGate unitFortiGate log information : traffic log with firewall policy of 0 (zero) "policyid=0"
- Is traffic arriving to the FortiGate and does it arrive on the expected port? r/fortinet: Discussing all things Fortinet. Used to set the differentiated services code point (DSCP) value that the FortiGate unit will apply to the field of reply (reverse) packets. id=20085 trace_id=319 func=fw_forward_handler line=248 msg=" Denied by forward policy check" 3.2 - The following is an example of debug flow output for traffic going into an IPSec tunnel in Policy based. NOTE: With the diag debug flow, if you see "Denied by forward policy check", than that means you hit a policy with the action either set to disable or you have no policy to begin with.

I noticed today that the 6.2 training has this message now "This class is being retired and replaced by NSE 4 FortiGate Security 6.4" If anyone is interested, the 6.4 training is alive and active in the training portal now.
