INCIDENT #074 · SECURITY
The policy is correct on the wrong interface
Hard25 minutesPro lab
The incident
The application edge's inbound ACL allows HTTPS, but the actual HTTPS path is still denied. Investigate where the core forwards application traffic and which outbound policy it applies.
Your objective
Restore the documented application transport flows and return reachability. Keep SSH blocked, preserve the working telemetry branch, and do not remove security boundaries or change interface addresses.
