IKE control-channel establishment is not equivalent to permitted encrypted application forwarding explains a different situation, phase-one up but no payload traffic, where both peers show an established IKE SA yet applications fail because no relevant phase-two or firewall policy state exists. It does not account for the specific observed policy-based versus route-based vpn condition at Northbridge Insurance. The decisive mechanism here is: Policy-based and route-based IPsec have different policy and interface matching requirements.

A wizard's initial example selectors and permit addresses may not match every required protected network explains a different situation, vpn wizard group policy permissions, where a newly created wizard tunnel is reachable from one internal subnet but the wizard-generated policy does not include the second authorized subnet. It does not account for the specific observed policy-based versus route-based vpn condition at Northbridge Insurance. The decisive mechanism here is: Policy-based and route-based IPsec have different policy and interface matching requirements.

Tunnel selector and route scope decide which client packets use the encrypted corporate path explains a different situation, split tunnel protection for remote vpn, where a remote IPsec client is routed through headquarters for every internet destination although company policy only requires private application prefixes.

After an ISP address change the authorized peer reconnects and passes protected traffic would validate the separate control ipsec endpoint fqdn dynamic dns, not the fault reported for Northbridge Government Services. To confirm this correction, the team instead needs: The healthy primary carries ordinary traffic and an authorized fault selects backup. That is the observable check related to tunnel route distance to backup.

The authorized peer connects and a supervised unknown identity cannot establish an SA would validate the separate control ipsec remote peer authentication scope, not the fault reported for Northbridge Government Services. To confirm this correction, the team instead needs: The healthy primary carries ordinary traffic and an authorized fault selects backup. That is the observable check related to tunnel route distance to backup.

A test reaches both offices through distinct documented translated destinations would validate the separate control ipsec overlapping address conflict, not the fault reported for Northbridge Government Services.
