Container for the parameters to the {@link com.amazonaws.services.ec2.AmazonEC2#createNetworkAclEntry(CreateNetworkAclEntryRequest) CreateNetworkAclEntry operation}.
Creates an entry (i.e., rule) in a network ACL with a rule number you specify. Each network ACL has a set of numbered ingress rules and a separate set of numbered egress rules. When determining whether a packet should be allowed in or out of a subnet associated with the ACL, Amazon VPC processes the entries in the ACL according to the rule numbers, in ascending order.
Important: We recommend that you leave room between the rules (e.g., 100, 110, 120, etc.), and not number them sequentially (101, 102, 103, etc.). This allows you to easily add a new rule between existing ones without having to renumber the rules.
After you add an entry, you can't modify it; you must either replace it, or create a new entry and delete the old one.
For more information about network ACLs, go to Network ACLs in the Amazon Virtual Private Cloud User Guide.
