@acls = $ec2->describe_network_acls(-network_acl_id=>\@ids, -filter=>\%filters)

@acls = $ec2->describe_network_acls(\@network_acl_ids)

@acls = $ec2->describe_network_acls(%filters)

Provides information about network ACLs.

Returns a series of VM::EC2::VPC::NetworkAcl objects.

Optional parameters are:

-network_acl_id      -- ID of the network ACL(s) to return information on. 
                        This can be a string scalar, or an arrayref.

-filter              -- Tags and other filters to apply.

The filter argument is a hashreference in which the keys are the filter names, and the values are the match strings. Some filters accept wildcards.

There are a number of filters, which are listed in full at http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeNetworkAcls.html

Here is a alpha-sorted list of filter names: association.association-id, association.network-acl-id, association.subnet-id, default, entry.cidr, entry.egress, entry.icmp.code, entry.icmp.type, entry.port-range.from, entry.port-range.to, entry.protocol, entry.rule-action, entry.rule-number, network-acl-id, tag-key, tag-value, tag:key, vpc-id

$acl = $ec2->create_network_acl(-vpc_id=>$vpc_id)

$acl = $ec2->create_network_acl($vpc_id)

Creates a new network ACL in a VPC. Network ACLs provide an optional layer of security (on top of security groups) for the instances in a VPC.

Arguments:

-vpc_id            -- The VPC ID to create the ACL in

Retuns a VM::EC2::VPC::NetworkAcl object on success.

$boolean = $ec2->delete_network_acl(-network_acl_id=>$id)

$boolean = $ec2->delete_network_acl($id)

Deletes a network ACL from a VPC. The ACL must not have any subnets associated with it. The default network ACL cannot be deleted.

Arguments:

-network_acl_id    -- The ID of the network ACL to delete

Returns true on successful deletion.

$boolean = $ec2->create_network_acl_entry(%args)

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:

-network_acl_id       -- ID of the ACL where the entry will be created
                         (Required)
-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_range_from      -- The first port in the range.  Required if specifying
                         6 (TCP) or 17 (UDP) for the protocol.
-port_range_to        -- The last port in the range.  Required if specifying
                         6 (TCP) or 17 (UDP) for the protocol.

-port_from            -- Alias for -port_range_from

-port_to              -- Alias for -port_range_to

Returns true on successful creation.

$success = $ec2->delete_network_acl_entry(-network_acl_id=>$id, -rule_number =>$int, -egress =>$bool)

Deletes an ingress or egress entry (i.e., rule) from a network ACL.

Arguments:

-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.

Returns true on successful deletion.

$assoc_id = $ec2->replace_network_acl_association(-association_id=>$assoc_id, -network_acl_id=>$id)

Changes which network ACL a subnet is associated with. By default when you create a subnet, it's automatically associated with the default network ACL.

Arguments:

-association_id    -- The ID of the association to replace

-network_acl_id    -- The ID of the network ACL to associated the subnet with

Returns the new association ID.

$success = $ec2->replace_network_acl_entry(%args)
