Properties

Property	Type	Required	Editable	Description	Constraint
AclEntries	List	No	Yes	The rules of the network ACL.	You can configure up to 40 rules. For more information, see AclEntries properties.
Description	String	No	No	The description of the network ACL.	The description must be 1 to 256 characters in length. It cannot start with `http://` or `https://`.
NetworkAclName	String	No	No	The name of the network ACL.	The name must be 1 to 128 characters in length. It cannot start with `http://` or `https://`.

AclEntries syntax

"AclEntries": [
  {
    "Policy": String,
    "PortRange": String,
    "Description": String,
    "Priority": Integer,
    "CidrBlock": String,
    "Protocol": String,
    "NetworkAclEntryName": String,
    "Direction": String
  }
]

AclEntries properties

Property	Type	Required	Editable	Description	Constraint
CidrBlock	String	Yes	Yes	The source CIDR block.	None.
Direction	String	Yes	Yes	The direction in which the rule is applied.	Valid values: ingress: inbound egress: outbound
Policy	String	Yes	Yes	The action to be performed on network traffic that matches the rule.	Valid values: accept: allows network traffic. drop: denies network traffic.
PortRange	String	Yes	Yes	The port range.	Valid value when Protocol is set to all or icmp: -1/-1. A value of -1/-1 specifies all ports. Value format when Protocol is set to tcp or udp: X/Y. X specifies the start port and Y specifies the end port. X and Y range from 1 to 65535. For example, 1/200 specifies port 1 to port 200 and 80/80 specifies port 80.
Priority	Integer	Yes	Yes	The priority of the rule.	Valid values: 1 to 100. Default value: 1.
Protocol	String	Yes	Yes	The protocol type.	Valid values: icmp tcp udp all
Description	String	No	No	The description of the network ACL.	The description must be 1 to 256 characters in length. It cannot start with `http://` or `https://`.
NetworkAclEntryName	String	No	No	The rule name.	The name must be 1 to 128 characters in length and cannot start with `http://` or `https://`.

Return values
