Fortinet FCP_FGT_AD-7.6 Questions & Answers

Ordinary port-overload source NAT may rewrite transport ports to maintain translation uniqueness explains a different situation, fixed-port source nat requirement, where a legacy voice integration breaks when the firewall changes a source UDP port that the partner protocol expects to remain stable. It does not account for the specific observed local-in versus forwarded traffic condition at Dunwell Insurance. The decisive mechanism here is: Traffic targeting FortiGate control-plane services is governed differently from transit traffic.

Stateful DNAT sessions depend on return packets reaching the translating firewall context explains a different situation, nat return path selection, where a server's inbound DNAT service works for SYN packets but response traffic escapes a different gateway outside the FortiGate session path. It does not account for the specific observed local-in versus forwarded traffic condition at Dunwell Insurance. The decisive mechanism here is: Traffic targeting FortiGate control-plane services is governed differently from transit traffic.

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.

The decisive mechanism here is: Policy-based NGFW uses central SNAT rather than relying on traditional per-policy source NAT controls.

A test server egress uses its assigned public address while ordinary clients use the shared pool would validate the separate control central snat rule precedence, not the fault reported for Dunwell Government Services. To confirm this correction, the team instead needs: An authorized outbound test shows the correct translated source address and matched security rule. That is the observable check related to central nat interaction with policy mode.

Traffic tests show the planned translated addresses before and after the change would validate the separate control central nat migration testing, not the fault reported for Dunwell Government Services. To confirm this correction, the team instead needs: An authorized outbound test shows the correct translated source address and matched security rule.

A controlled user session produces appropriate accounting start and stop context would validate the separate control radius accounting visibility, not the fault reported for Dunwell Government Services. To confirm this correction, the team instead needs: An authorized outbound test shows the correct translated source address and matched security rule. That is the observable check related to central nat interaction with policy mode.

Check specific-to-general ordering when adding central NAT mappings reduces recurrence of central snat rule precedence, rather than the observed central nat interaction with policy mode issue.
