Container for the parameters to the CreateNetworkAclEntry operation. Creates an entry (a rule) in a network ACL with the specified rule number. 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, we process the entries in the ACL according to the rule numbers, in ascending order. Each network ACL has a set of ingress rules and a separate set of egress rules.

We recommend that you leave room between the rule numbers (for example, 100, 110, 120, ...), and not number them one right after the other (for example, 101, 102, 103, ...). This makes it easier to add a 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 an entry and delete the old one.

For more information about network ACLs, see Network ACLs in the Amazon VPC User Guide.

The CreateNetworkAclEntryRequest type exposes the following members

Constructors

Properties

NameTypeDescription
Public Property CidrBlock System.String

Gets and sets the property CidrBlock.

The IPv4 network range to allow or deny, in CIDR notation (for example 172.16.0.0/24). We modify the specified CIDR block to its canonical form; for example, if you specify 100.68.0.18/18, we modify it to 100.68.0.0/18.

Public Property Egress System.Boolean

Gets and sets the property Egress.

Indicates whether this is an egress rule (rule is applied to traffic leaving the subnet).

Public Property IcmpTypeCode Amazon.EC2.Model.IcmpTypeCode

Gets and sets the property IcmpTypeCode.

ICMP protocol: The ICMP or ICMPv6 type and code. Required if specifying protocol 1 (ICMP) or protocol 58 (ICMPv6) with an IPv6 CIDR block.

Public Property Ipv6CidrBlock System.String

Gets and sets the property Ipv6CidrBlock.

The IPv6 network range to allow or deny, in CIDR notation (for example 2001:db8:1234:1a00::/64).

Public Property NetworkAclId System.String

Gets and sets the property NetworkAclId.

The ID of the network ACL.

Public Property PortRange Amazon.EC2.Model.PortRange

Gets and sets the property PortRange.

TCP or UDP protocols: The range of ports the rule applies to. Required if specifying protocol 6 (TCP) or 17 (UDP).

Public Property Protocol System.String

Gets and sets the property Protocol.

The protocol number. A value of "-1" means all protocols. If you specify "-1" or a protocol number other than "6" (TCP), "17" (UDP), or "1" (ICMP), traffic on all ports is allowed, regardless of any ports or ICMP types or codes that you specify. If you specify protocol "58" (ICMPv6) and specify an IPv4 CIDR block, traffic for all ICMP types and codes allowed, regardless of any that you specify. If you specify protocol "58" (ICMPv6) and specify an IPv6 CIDR block, you must specify an ICMP type and code.

Public Property RuleAction Amazon.EC2.RuleAction

Gets and sets the property RuleAction.

Indicates whether to allow or deny the traffic that matches the rule.

Public Property RuleNumber System.Int32

Gets and sets the property RuleNumber.

The rule number for the entry (for example, 100). ACL entries are processed in ascending order by rule number.

Constraints: Positive integer from 1 to 32766. The range 32767 to 65535 is reserved for internal use.

Examples

This example creates an entry for the specified network ACL. The rule allows ingress traffic from anywhere (0.0.0.0/0) on UDP port 53 (DNS) into any associated subnet.

To create a network ACL entry


var client = new AmazonEC2Client();
var response = client.CreateNetworkAclEntry(new CreateNetworkAclEntryRequest 
{
    CidrBlock = "0.0.0.0/0",
    Egress = false,
    NetworkAclId = "acl-5fb85d36",
    PortRange = new PortRange {
        From = 53,
        To = 53
    },
    Protocol = "17",
    RuleAction = "allow",
    RuleNumber = 100
});
