The Firewall That Never Saw the Request
Replies are dropped by a firewall that never saw the request.
Escenario
Lowell Actuarial added a second path between its server room and the core for resilience. Since then the reporting client cannot reach the analytics server, although the server records the incoming requests and answers them. The security team confirms the return firewall is configured exactly as approved and refuses to loosen it. Restore client access without weakening the firewall.
