+## Chain virtual machine to Gateway Load Balancer
+
+Alternatively, you can chain a VM's NIC IP configuration to the gateway load balancer. 
+
+You'll add the gateway load balancer's frontend to an existing VM's NIC IP configuration.
+
+Use [az network lb frontend-ip show](/cli/azure/network/lb/frontend-ip#az_az_network_lb_frontend_ip_show) to place the resource ID of your gateway load balancer frontend into a variable.
+
+Use [az network lb frontend-ip update](/cli/azure/network/nic/ip-config#az-network-nic-ip-config-update) to chain the gateway load balancer frontend to your existing VM's NIC IP configuration.
+
+```azurecli-interactive
+ feid=$(az network lb frontend-ip show \
+    --resource-group TutorGwLB-rg \
+    --lb-name myLoadBalancer-gw \
+    --name myFrontend \
+    --query id \
+    --output tsv)
+    
+  az network nic ip-config update \
+    --resource-group MyResourceGroup
+    --nic-name MyNIC 
+    --name MyIPconfig 
+    --gateway-lb $feid
+
+```

 ## Clean up resources
 
 When no longer needed, you can use the [az group delete](/cli/azure/group#az_group_delete) command to remove the resource group, load balancer, and the remaining resources.
