Create a network ACL

Overview

A network access control list (ACL) allows you to manage network access in a virtual private cloud (VPC). You can create a network ACL in a VPC and add inbound and outbound rules to the network ACL. After you create a network ACL, you can associate it with a VSwitch. This way, you can use the network ACL to control the traffic that flows through the Elastic Compute Service (ECS) instances that are connected to the VSwitch.

Procedure

1. In the left-side navigation pane, choose ACL > Network ACL.
   
2. On the Network ACL page, click Create Network ACL.
   
3. In the Create Network ACL dialog box, input the parameters and click OK.
