VM::EC2::VPC::NetworkAcl - Virtual Private Cloud network ACL
SYNOPSIS
use VM::EC2;
my $ec2 = VM::EC2->new(...);
my @acls = $ec2->describe_network_acls(-network_acl_id=>'acl-12345678');
foreach my $acl (@acls) {
my $vpc_id = $acl->vpcId;
my $default = $acl->default;
my @entries = $acl->entries;
my @assoc = $acl->associations;
...
}
my $acl = $ec2->create_network_acl_entry(...);
DESCRIPTION
This object represents an Amazon EC2 VPC network ACL, and is returned by
VM::EC2->describe_network_acls() and ->create_network_acl()
METHODS
These object methods are supported:
networkAclId -- The network ACL's ID.
vpcId -- The ID of the VPC the network ACL is in.
default -- Whether this is the default network ACL in the VPC.
entrySet -- A list of entries (rules) in the network ACL.
associationSet -- A list of associations between the network ACL and
one or more subnets.
tagSet -- Tags assigned to the resource.
associations -- Alias for associationSet.
entries -- Alias for entrySet.
The object also supports the tags() method described in VM::EC2::Generic:
CONVENIENCE METHODS
$success = $acl->create_entry(%args) =head2 $success = $acl->create_entry($acl_entry)
Creates an entry (i.e., rule) in a network ACL with the rule number you specified. 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.
Arguments:
-rule_number -- Rule number to assign to the entry (e.g., 100).
ACL entries are processed in ascending order by
rule number. Positive integer from 1 to 32766.
(Required)
-protocol -- The IP protocol the rule applies to. You can use
-1 to mean all protocols. See
http://www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml
for a list of protocol numbers. (Required)
-rule_action -- Indicates whether to allow or deny traffic that
matches the rule. allow | deny (Required)
-egress -- Indicates whether this rule applies to egress
traffic from the subnet (true) or ingress traffic
to the subnet (false). Default is false.
-cidr_block -- The CIDR range to allow or deny, in CIDR notation
(e.g., 172.16.0.0/24). (Required)
-icmp_code -- For the ICMP protocol, the ICMP code. You can use
-1 to specify all ICMP codes for the given ICMP
type. Required if specifying 1 (ICMP) for protocol.
-icmp_type -- For the ICMP protocol, the ICMP type. You can use
-1 to specify all ICMP types. Required if
specifying 1 (ICMP) for the protocol
-port_from -- The first port in the range. Required if specifying
6 (TCP) or 17 (UDP) for the protocol.
-port_to -- The last port in the range. Required if specifying
6 (TCP) or 17 (UDP) for the protocol.
Alternately, can pass an existing ACL entry object VM::EC2::VPC::NetworkAcl::Entry as the
only argument for ease in copying entries from one ACL to another.
Returns true on successful creation.
$success = $acl->delete_entry(%args) =head2 $success = $acl->delete_entry($acl_entry)
Deletes an ingress or egress entry (i.e., rule) from a network ACL.
Arguments:
-network_acl_id -- ID of the ACL where the entry will be created
-rule_number -- Rule number of the entry (e.g., 100).
Optional arguments:
-egress -- Whether the rule to delete is an egress rule (true) or ingress
rule (false). Default is false.
Alternately, can pass an existing ACL entry object VM::EC2::VPC::NetworkAcl::Entry as the
only argument to ease deletion of entries.
Returns true on successful deletion.
$success = replace_entry(%args) =head2 $success = replace_entry($acl_entry)
Replaces an entry (i.e., rule) in a network ACL.
Arguments:
-network_acl_id -- ID of the ACL where the entry will be created
(Required)
-rule_number -- Rule number of the entry to replace. (Required)
-protocol -- The IP protocol the rule applies to. You can use
-1 to mean all protocols. See
http://www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml
for a list of protocol numbers. (Required)
-rule_action -- Indicates whether to allow or deny traffic that
matches the rule. allow | deny (Required)
-egress -- Indicates whether this rule applies to egress
traffic from the subnet (true) or ingress traffic
to the subnet (false). Default is false.
-cidr_block -- The CIDR range to allow or deny, in CIDR notation
(e.g., 172.16.0.0/24). (Required)
-icmp_code -- For the ICMP protocol, the ICMP code. You can use
-1 to specify all ICMP codes for the given ICMP
type. Required if specifying 1 (ICMP) for protocol.
-icmp_type -- For the ICMP protocol, the ICMP type. You can use
-1 to specify all ICMP types. Required if
specifying 1 (ICMP) for the protocol
-port_from -- The first port in the range. Required if specifying
6 (TCP) or 17 (UDP) for the protocol.
-port_to -- The last port in the range. Only required if
specifying 6 (TCP) or 17 (UDP) for the protocol and
is a different port than -port_from.
Alternately, can pass an existing ACL entry object VM::EC2::VPC::NetworkAcl::Entry as the
only argument for ease in replacing entries from one ACL to another. The rule number in
the passed entry object must already exist in the ACL.
Returns true on successful replacement.
$association_id = $acl->associate($subnet_id)
Associates the ACL with a subnet in the same VPC. Replaces whatever ACL the subnet was
associated with previously.
$association_id = $acl->disassociate($subnet_id)
Disassociates the ACL with a subnet in the same VPC. The subnet will then be associated
with the default ACL.
STRING OVERLOADING
When used in a string context, this object will interpolate the networkAclId.
