+## Show the outbound rule for your load balancer
+
+To show the outbound rule created in the load balancer, use [az network lb outbound-rule list][az-network-lb-outbound-rule-list] and specify the node resource group of your AKS cluster:
+
+```azurecli-interactive
+NODE_RG=$(az aks show --resource-group myResourceGroup --name myAKSCluster --query nodeResourceGroup -o tsv)
+az network lb outbound-rule list --resource-group $NODE_RG --lb-name kubernetes -o table
+```
+
+The previous commands will list the outbound rule for your load balancer, for example:
+
+```console
+AllocatedOutboundPorts    EnableTcpReset    IdleTimeoutInMinutes    Name             Protocol    ProvisioningState    ResourceGroup
+------------------------  ----------------  ----------------------  ---------------  ----------  -------------------  -------------
+0                         True              30                      aksOutboundRule  All         Succeeded            MC_myResourceGroup_myAKSCluster_eastus  
+```
+
+In the example output, *AllocatedOutboundPorts* is 0. The value for *AllocatedOutboundPorts* means that SNAT port allocation reverts to automatic assignment based on backend pool size. See [Load Balancer outbound rules][azure-lb-outbound-rules] and [Outbound connections in Azure][azure-lb-outbound-connections] for more details.
