Línea de trabajo

Comienza reproduciendo Get-MgBetaNetworkAccessForwardingPolicyRule con el ID de la política de reenvío indicado e inspecciona la respuesta de GET /beta/networkAccess/forwardingPolicies/{id}/policyRules. Compara el array de valores vacío con los segmentos de aplicación existentes de la política en el Microsoft Entra admin center; se considera terminado cuando se devuelven las reglas configuradas, incluidos los datos disponibles de IP, FQDN, puerto y protocolo, o cuando se identifica claramente el comportamiento del SDK.

Descripción

Service issue Status: Needs Investigation type:bug
Describe the bug

When querying for the rules of a specific, valid forwarding policy ID using Get-MgBetaNetworkAccessForwardingPolicyRule, the Graph API successfully returns a 200 OK status code. However, the body of the response incorrectly contains an empty value array ("value": []), even when the policy has numerous rules (application segments) visible in the Microsoft Entra admin center.

This behavior makes it impossible to automate the enumeration of all FQDNs and IP ranges within Private Access, as the API is not returning the configured data.

Expected behavior

List the rules for the policy? Display the IP and FQDN, possibly the Ports and protocol.

How to reproduce
Connect-MgGraph -Scopes "NetworkAccess.Read.All"
# Get all policies and select one for testing
$policies = Get-MgBetaNetworkAccessForwardingPolicy | Where-Object { $_.TrafficForwardingType -eq 'private' }
$testPolicyId = $policies[0].Id
Get-MgBetaNetworkAccessForwardingPolicyRule -ForwardingPolicyId $testPolicyId
SDK Version
