Enabling or Disabling a Network ACL

After a network ACL is created, it is enabled by default. You can disable it as required.

• If a network ACL is disabled, custom rules become invalid, but the default rules are still applied. As a result, all traffic to and from the associated subnets is denied. If a network ACL has a subnet associated, disabling it will interrupt the network traffic to and from the subnet.
• If a network ACL is enabled, both custom and default rules are applied. If a network ACL has a subnet associated and has only default rules, enabling it will interrupt the network traffic to and from the subnet.
