Fine tune the profiles/policy recently added/removed, so that it allows the traffic.No: Check why the traffic is blocked, per below, and note what is observed. Export a small group of such logs from the logging unit (FortiGate GUI, FortiAnalyzer, FortiCloud, Syslog, etc).Packet capture (sniffer): On models with hardware acceleration, this has to be disabled temporarily in order to capture the traffic.It is better captured from command line and log the SSH output.Debug flow (firewall logic): Common cases where traffic is not passing, and shown in debug flow for new sessions:'Denied by forward policy check'. Before you can determine if the logs indicate a problem, you need to know what logs result from normal operation. 3. Filter or order log entries based on different fields, such as level, service, or IP address, to look for patterns that may indicate a specific problem, such as frequent blocked connections on a specific port for all IP addresses. Enable/disable override FortiAnalyzer settings. 3. Without a baseline it is difficult to properly troubleshoot. Local traffic is traffic that originates or terminates on the FortiGate itself - when it initiates connections to DNS servers, contacts FortiGuard, administrative access, VPNs, communication with authentication servers and similar. Logs will help identify and locate any problems, but they will not solve the problems. Home FortiGate / FortiOS 6.4.4 CLI Reference. The event log records administration management as well as Fortinet device system activity, such as when a configuration has changed, admin login, or high availability (HA) events occur. Aggregation mode configurations are not listed in the GUI table, but still use a log forwarding ID number. No configuration is needed on the server side. To register devices, see Adding devices manually. Table of Contents. Does it work after reverting the previous changes?Yes: The root cause is isolated.

Settings for this are available via CLI (disabled by default): Enable/disable inserting policy comments into traffic logs. Enter the IP address of the remote server. To compile an accurate risk assessment and provide forensic analysis, it is essential for security personnel to know where events occurred, such as network element components, modules, device identifiers, node names, and functionality. By 2. If FortiGate logs are too large, you can turn off or scale back the logging for features that are not in use. You should log as much information as possible when you first configure FortiOS. You should log as much information as possible when you first configure FortiOS. .. are the same as in FortiOS 6.2 (listed bellow), but adds following new categories: .. are the same as in FortiOS 6.2 (listed bellow), but adds following new category: The default log filter configuration looks like below. Go to System Settings > Log Forwarding. This fix can be performed on the FortiGate GUI or on the CLI. This log is needed when creating a TAC support case.- Start with the policy that is expected to allow the traffic. Compare current logs to a recorded baseline of normal operation. Associating information about where the event occurred within the network provides a means of investigating an attack, recognizing resource utilization or capacity thresholds, or identifying an improperly configured network element.

FortiGate, FortiCarrier, FortiMail, FortiWeb, and FortiClient logging is supported. In aggregation mode, accepting the logs must be enabled on the FortiAnalyzer that is acting as the server. When available, the logs are the most accessible way to check why traffic is blocked. Add filters to the table by selecting the Log Field, Match Criteria, and Value for each filter. Enable log aggregation and, if necessary, configure the disk quota, with the following CLI commands: Create a new, or edit an existing, log forwarding entry: Set the server display name and IP address: Enter the user name and password of the super user administrator on the server: If required, set the aggregation time from 0 to 23 hours (default: 0, or midnight): Enter the following to apply the configuration and create the log aggregation.
