Request Syntax

response = client.replace_network_acl_entry(
    CidrBlock='string',
    DryRun=True|False,
    Egress=True|False,
    IcmpTypeCode={
        'Code': 123,
        'Type': 123
    },
    Ipv6CidrBlock='string',
    NetworkAclId='string',
    PortRange={
        'From': 123,
        'To': 123
    },
    Protocol='string',
    RuleAction='allow'|'deny',
    RuleNumber=123
)
Parameters:

  • CidrBlock (string) – The IPv4 network range to allow or deny, in CIDR notation (for example 172.16.0.0/24).

  • DryRun (boolean) – Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

  • Egress (boolean) –

    [REQUIRED]

    Indicates whether to replace the egress rule.

    Default: If no value is specified, we replace the ingress rule.

  • IcmpTypeCode (dict) –

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

    • Code (integer) –

      The ICMP code. A value of -1 means all codes for the specified ICMP type.

    • Type (integer) –

      The ICMP type. A value of -1 means all types.

  • Ipv6CidrBlock (string) – The IPv6 network range to allow or deny, in CIDR notation (for example 2001:bd8:1234:1a00::/64).

  • NetworkAclId (string) –

    [REQUIRED]

    The ID of the ACL.

  • PortRange (dict) –

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

    • From (integer) –

      The first port in the range.

    • To (integer) –

      The last port in the range.

  • Protocol (string) –

    [REQUIRED]

    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.

  • RuleAction (string) –

    [REQUIRED]

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

  • RuleNumber (integer) –

    [REQUIRED]

    The rule number of the entry to replace.

Returns:

None

Examples

This example replaces an entry for the specified network ACL. The new rule 100 allows ingress traffic from 203.0.113.12/24 on UDP port 53 (DNS) into any associated subnet.

response = client.replace_network_acl_entry(
    CidrBlock='203.0.113.12/24',
    Egress=False,
    NetworkAclId='acl-5fb85d36',
    PortRange={
        'From': 53,
        'To': 53,
    },
    Protocol='17',
    RuleAction='allow',
    RuleNumber=100,
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
