I am using Fortigate 400E with FortiOS v6.4.2, the VIP configuration ( VIP portforwarding + NAT enabled ); And I found the "no session matched" eventlog as below: session captured ( public IPs are modified): id=20085 trace_id=41913 func=print_pkt_detail line=5639 msg="vd-root:0 received a packet(proto=6, 100.100.100.154:45742->111.111.111.248:18889) from port2. ], seq 3567147422, ack 2872486997, win 8192" This means that your clients and netstat output will still show a connection state of 'ESTABLISHED' while your Fortigate debugs will show 'No session found', meaning the service needs to wait for the TCP timeouts to occur before building a new session. 08-07-2014 In both cases it was tracked back to FSSO.

For TCP, the first number (from left to right) is related to the server-side state and is 0 when the session is not subject to any inspection (flow or proxy). Maybe you could update the FOS to 4.3.17, just to make sure4.3.9 is quite old.

WebEnsure the exact matching denied traffic is used on the policy lookup. While they are being removed from the session table logs with the 'unknown-0' src/dst interface are generated.2) These log messages are also known to be seen, when a packet comes to a FortiGate and FortiOS and can't find an existing session for it, although it is expected that it has to be in place.Below are two examples of such scenario:- When FortiGate receives a TCP FIN packet, and there is no session, which this packet can match.An example of such scenario can be a TCP session removed from the session table after session-ttl value is expired for it. If i understand that right that should allow any traffic outbound. 06-14-2022 In such case, if for any reason client still sends packets related to the removed session, packets are dropped due to implicit deny" policy (ID 0) match and 'unknown-0' log message is generated.In both examples No Session Match messages are seen in the debug flow logs.Related article: Technical Tip: 'No Session Match' error and halfclose timer, The Fortinet Security Fabric brings together the concepts of convergence and consolidation to provide comprehensive cybersecurity protection for all users, devices, and applications and across all network edges.. This article provides an explanation of various fields of the FortiGate session table.

If you debug flow for long enough do you get something like 'session not matched' ? When a session is closed by both sides, FortiGate keeps that session in the session table for a few seconds more, to allow for any out-of-order packets that might arrive after the FIN/ACK packet. It's apparently fixed in 6.2.4 if you want to roll the dice.

this could be routing info missing. Seeing that this box was factory defaulted and doesn't h active lic in it would there be a max device count or something?

The traffic log from the FortiAnalyzer showed the packets being denied for reason code No session matched. Fabulous. By tos:a) The policy has tos/dscp configured to override this value on a packet.b) A proxy-based feature is enabled and it is necessary to preserve the tos/dscp on packets in the flow by caching the tos/dscp on the kernel session from the original packet and then setting it on any subsequent packets that are generated by the proxy. Thanks for the reply.

Thanks for the help! Does this help troubleshoot the issue in any way? The typical symptoms are "no session matched" in debug flow (since the session gets removed abruptly and new packets don't match the no-longer-existing session), and the traffic session being logged as closed with a timeout (if you log the sessions at all).The usual trigger has been FSSO session changes, so this is a good check for quick triage. WebIf you just enable NAT to the interface on your firewall policy and don't preserve source port, the FG should do source port NAT and prevent session clashes. We only have half that.
