Question 430
At Fairmont Regional Hospital, the FortiGate 7.6 security administration team encounters the following authorized operational case: a profile-based firewall moves from policy SNAT to central SNAT and some published application flows lose their intended identity. They need a defensible FortiOS configuration, diagnosis, validation or prevention decision. What root condition most directly explains the described FortiGate symptom?
Explanation
Correct Answer
Changing NAT control location can leave implicit per-policy translation behavior unrepresented. The mechanism is relevant because the stated central nat migration testing incident concerns the actual selected path, policy, identity or inspection state. The appropriate response is to build and validate equivalent central SNAT mappings for affected traffic before switching modes; verify it through this observed condition: traffic tests show the planned translated addresses before and after the change.
Incorrect Answers
A backup identity server is ineffective when its address, route or retry behavior is misconfigured explains a different situation, radius timeout and failover, where valid users fail authentication during a primary RADIUS server outage despite a configured secondary server. It does not account for the specific observed central nat migration testing condition at Fairmont Regional Hospital. The decisive mechanism here is: Changing NAT control location can leave implicit per-policy translation behavior unrepresented.
Guest credentials without enforced expiry can outlast the intended access window explains a different situation, guest account expiration, where short-term contractors continue to authenticate through old FortiGate guest identities after their authorized engagement ends. It does not account for the specific observed central nat migration testing condition at Fairmont Regional Hospital. The decisive mechanism here is: Changing NAT control location can leave implicit per-policy translation behavior unrepresented.
A collector cannot infer logons that never reach any configured event or agent source explains a different situation, fsso domain-controller agent collection, where domain users intermittently lose identity mapping after their logons move to a domain controller that lacks the FSSO agent. It does not account for the specific observed central nat migration testing condition at Fairmont Regional Hospital. The decisive mechanism here is: Changing NAT control location can leave implicit per-policy translation behavior unrepresented.
