Overview

This object represents an Amazon EC2 VPC network ACL entry

Methods

These object methods are supported:

 ruleNumber     -- Specific rule number for the entry. ACL entries are
                   processed in ascending order by rule number.
 protocol       -- Protocol. A value of -1 means all protocols.
                   See: http://www.iana.org/assignments/protocol-numbers/protocol-numbers.xml
                   for a list of protocol numbers.
 ruleAction     -- Whether to allow or deny the traffic that matches the
                   rule.  Valid values:  allow | deny
 egress         -- Boolean flag to indicate an egress rule (rule is
                   applied to traffic leaving the subnet). Value of true
                   indicates egress.
 cidrBlock      -- The network range to allow or deny, in CIDR notation.
 icmpType       -- For the ICMP protocol, this is the ICMP type
 icmpCode       -- For the ICMP protocol, this is the ICMP code.
 portRangeFrom  -- For the TCP or UDP protocols, the starting range of ports the
                   rule applies to.
 portRangeTo    -- For the TCP or UDP protocols, the ending range of ports the
                   rule applies to.
 port_from      -- Alias for portRangeFrom
 port_to        -- Alias for portRangeTo

The object also supports the tags() method described in VM::EC2::Generic:

String overloading

When used in a string context, this object will interpolate the rule number
