Question 390
At Eastvale Insurance, the FortiGate 7.6 security administration team encounters the following authorized operational case: a FortiGate central SNAT configuration translates a restricted server through the general internet pool instead of its assigned pool. They need a defensible FortiOS configuration, diagnosis, validation or prevention decision. What root condition most directly explains the described FortiGate symptom?
Explanation
Correct Answer
Central source NAT rules are evaluated by their match criteria and ordering. The mechanism is relevant because the stated central snat rule precedence incident concerns the actual selected path, policy, identity or inspection state. The appropriate response is to place or refine the specific central SNAT rule ahead of overlapping broader entries; verify it through this observed condition: a test server egress uses its assigned public address while ordinary clients use the shared pool.
Incorrect Answers
An LDAP connector cannot search users through an invalid service bind even if the user passwords are correct explains a different situation, ldap bind account permissions, where fortiGate LDAP authentication begins failing after the enterprise directory bind account is disabled. It does not account for the specific observed central snat rule precedence condition at Eastvale Insurance. The decisive mechanism here is: Central source NAT rules are evaluated by their match criteria and ordering.
An ordinary source-address permit rule does not force the end user to complete interactive authentication explains a different situation, captive portal active authentication, where guest wireless clients pass the firewall to a restricted website without ever being prompted for required login. It does not account for the specific observed central snat rule precedence condition at Eastvale Insurance. The decisive mechanism here is: Central source NAT rules are evaluated by their match criteria and ordering.
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 snat rule precedence condition at Eastvale Insurance. The decisive mechanism here is: Central source NAT rules are evaluated by their match criteria and ordering.
