Verify the collector group filters and FortiGate FSSO group mapping configuration could correct a different FortiGate problem, such as when an FSSO collector shows an active user but the FortiGate firewall policy cannot see the user's group. The current case requires use the SD-WAN zone as the relevant policy egress interface with the approved source and services for its particular control path.

Enable source NAT using the permitted outbound interface address on the matching policy could correct a different FortiGate problem, such as when multiple private office clients need internet access through a single FortiGate public WAN interface. The current case requires use the SD-WAN zone as the relevant policy egress interface with the approved source and services for its particular control path.

Here the relevant FortiOS behavior is that cloud-native firewall controls require both explicit traffic steering and correct security policy enforcement.

After a controlled workstation switch the old IP mapping expires and the new host is mapped could show improvement in a separate Fortinet case, for instance when an employee changes computers and FSSO grants the old workstation the same access for an extended period. The actual verification here is that a test collector outage still produces new valid FSSO logon records through the backup.

Sessions continue through healthy members of the designated zone while the expected policy matches could show improvement in a separate Fortinet case, for instance when a branch uses an SD-WAN zone with two WAN members but its firewall policy names only a member interface. The actual verification here is that a test collector outage still produces new valid FSSO logon records through the backup.

The encrypted LDAP connection validates the expected certificate and authenticates test users could show improvement in a separate Fortinet case, for instance when a business wants external identity verification but does not want plaintext directory passwords sent across the WAN. The actual verification here is that a test collector outage still produces new valid FSSO logon records through the backup.

Create the correct VLAN subinterface under the parent port and permit it on the switch trunk could correct a different FortiGate problem, such as when a FortiGate is connected to a trunk switch but a new department tag never reaches its firewall policy. The current case requires inspect FortiGuard entitlement status and reachability to approved FortiGuard distribution servers for its particular control path.

Design FortiSASE user onboarding and secure access policies for supported endpoint connectivity could correct a different FortiGate problem, such as when a distributed company needs to apply cloud-delivered security checks to remote users outside branch offices. The current case requires inspect FortiGuard entitlement status and reachability to approved FortiGuard distribution servers for its particular control path.

Configure an authorized external syslog or FortiAnalyzer destination with retention controls could correct a different FortiGate problem, such as when the firewall has limited local storage but auditors require logs beyond the appliance retention window. The current case requires inspect FortiGuard entitlement status and reachability to approved FortiGuard distribution servers for its particular control path.

Packet capture distinguishes transport handshakes from ICMP reachability and policy routing effects describes a distinct situation, for example when a server is reachable by ping but HTTPS sessions are reset across one FortiGate interface. Here the relevant FortiOS behavior is that remote logging extends evidence retention beyond the capacity and rotation rules of local memory storage.

An interface IP address does not itself supply a next hop for destinations outside connected subnets describes a distinct situation, for example when a branch FortiGate has no configured default route after its WAN address is assigned. Here the relevant FortiOS behavior is that remote logging extends evidence retention beyond the capacity and rotation rules of local memory storage.

Cloud-native firewall controls require both explicit traffic steering and correct security policy enforcement describes a distinct situation, for example when a cloud team plans to use a FortiGate CNF deployment but omits workload association and route checks. Here the relevant FortiOS behavior is that remote logging extends evidence retention beyond the capacity and rotation rules of local memory storage.

System status and interface diagnostics establish the actual software and network state before changing policies describes a distinct situation, for example when a FortiGate administrator needs the interface status and build version before opening a troubleshooting case. Here the relevant FortiOS behavior is that a release upgrade path protects configuration compatibility across firmware transitions.

Cloud-managed policy administration decouples remote-user inspection from branch firewall administrator access describes a distinct situation, for example when a business wants to enforce consistent web security for contractors without making them administrators of local FortiGates. Here the relevant FortiOS behavior is that a release upgrade path protects configuration compatibility across firmware transitions.

FGCP membership requires compatible members and shared HA configuration for election and synchronization describes a distinct situation, for example when two FortiGates refuse to join the same FGCP high-availability cluster after installation. Here the relevant FortiOS behavior is that a release upgrade path protects configuration compatibility across firmware transitions.

Using outdated IP mappings may grant policy access to a different person reusing the same address can be a real concern elsewhere, such as when an employee changes computers and FSSO grants the old workstation the same access for an extended period. In the present scenario the key failure is that two broad conflicting VIP mappings on the same public address and port cannot distinguish services.

A stale authenticated session or obsolete group mapping can extend previously granted access can be a real concern elsewhere, such as when an authenticated staff member can access a restricted application despite having left the approved department. In the present scenario the key failure is that two broad conflicting VIP mappings on the same public address and port cannot distinguish services.

Creating a firewall group name without functional LDAP connectivity cannot prove user credentials can be a real concern elsewhere, such as when employees authenticate with a corporate directory but FortiGate has no LDAP server connector configured. In the present scenario the key failure is that two broad conflicting VIP mappings on the same public address and port cannot distinguish services.

IPsec Phase 1 negotiates a compatible secure IKE association before establishing protected data traffic describes a distinct situation, for example when a branch FortiGate and a partner gateway fail IKE negotiation after administrators choose incompatible encryption proposals. Here the relevant FortiOS behavior is that stateful private traffic needs compatible forward and reverse paths through negotiated IPsec interfaces.

IPsec IKE negotiation requires contact with the intended reachable peer network endpoint describes a distinct situation, for example when a backup IPsec peer remains configured after the retired partner gateway changes its public address. Here the relevant FortiOS behavior is that stateful private traffic needs compatible forward and reverse paths through negotiated IPsec interfaces.

IPsec routing and FortiGate forwarding policy authorizations are separate controls describes a distinct situation, for example when a FortiGate IPsec interface has an active route but private traffic is denied when it enters the VPN. Here the relevant FortiOS behavior is that stateful private traffic needs compatible forward and reverse paths through negotiated IPsec interfaces.

Application-control logs can correlate recognized protocol and application signatures with policy actions describes a distinct situation, for example when a security operations dashboard shows generic unknown applications and little useful detail for a new workload. Here the relevant FortiOS behavior is that antivirus scanning needs accessible downloaded content and compatible inspection processing.

Profile feature-set compatibility determines which flow-based and proxy-based filtering capabilities are usable describes a distinct situation, for example when a proxy-based web filter profile cannot be applied to a policy configured for an incompatible flow inspection mode. Here the relevant FortiOS behavior is that antivirus scanning needs accessible downloaded content and compatible inspection processing.

A URL filter string or wildcard matches only the host and path patterns specified by the rule describes a distinct situation, for example when a social media site has multiple subdomains but a web-filter exemption was configured using only one hostname. Here the relevant FortiOS behavior is that antivirus scanning needs accessible downloaded content and compatible inspection processing.

Rebooting the collector does not restore events intentionally filtered at the sender can be a real concern elsewhere, such as when after changing the logging severity filter FortiGate threat events stop appearing in a syslog collector. In the present scenario the key failure is that a screenshot of policy names does not recover address objects certificates or system interfaces.

Successful installation of an endpoint agent does not automatically authorize every private application can be a real concern elsewhere, such as when a remote laptop is registered in FortiSASE but is not assigned the correct user access entitlement. In the present scenario the key failure is that a screenshot of policy names does not recover address objects certificates or system interfaces.
