NAME

6       VM::EC2::SecurityGroup::IpPermission - Object describing a firewall
7       rule in an EC2 security group.

SYNOPSIS

10         $ec2      = VM::EC2->new(...);
11         $sg       = $ec2->describe_security_groups(-name=>'My Group');
12
13         my @rules = $sg->ipPermissions;
14         for my $rule (@rules) {   # each rule is a VM::EC2::SecurityGroup::IpPermission
15                $protocol = $rule->ipProtocol;
16                $fromPort = $rule->fromPort;
17                $toPort   = $rule->toPort;
18                @ranges   = $rule->ipRanges;
19                @groups   = $rule->groups;
20         }

DESCRIPTION

23       This object is used to describe the firewall rules defined within an
24       Amazon EC2 security group. It is returned by the VM::EC2::SecurityGroup
25       object's ipPermissions() and ipPermissionsEgress() methods (these are
26       also known as inbound_permissions() and outbound_permissions()).
27

METHODS

29   $protocol = $rule->ipProtocol
30       Return the IP protocol for this rule: one of "tcp", "udp" or "icmp".
31
32   $port = $rule->fromPort
33       Start of the port range defined by this rule, or the ICMP type code.
34       This will be a numeric value, like 80, or -1 to indicate all
35       ports/codes.
36
37   $port = $rule->toPort
38       End of the port range defined by this rule, or the ICMP type code. This
39       will be a numeric value, like 80, or -1 to indicate all ports/codes.
40
41   @ips = $rule->ipRanges
42       This method will return a list of the IP addresses that are allowed to
43       originate or receive traffic, provided that the rule defines IP-based
44       firewall filtering.
45
46       Each address is a CIDR (classless internet domain routing) address in
47       the form a.b.c.d/n, such as 10.23.91.0/24
48       (http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing). The
49       "any" address is in the form 0.0.0.0/0.
50
51   @groups = $rule->groups
52       This method will return a list of the security groups that are allowed
53       to originate or receive traffic from instances assigned to this
54       security group, provided that the rule defines group-based traffic
55       filtering.
56
57       Each returned object is a VM::EC2::SecurityGroup::GroupPermission, not
58       a VM::EC2::SecurityGroup. The reason for this is that these traffic
59       filtering groups can include security groups owned by other accounts
60
61       The GroupPermission objects define the methods userId(), groupId() and
62       groupName().
63

STRING OVERLOADING

65       When used in a string context, this object will interpolate the rule
66       using the following templates:
67
68       TCP port 22 open to any host:
69
70        "tcp(22..22) FROM CIDR 0.0.0.0/0"
71
72       TCP ports 23 through 39 open to the two class C networks 192.168.0.*
73       and 192.168.1.*:
74
75        "tcp(23..29) FROM CIDR 192.168.0.0/24,192.168.1.0/24"
76
77       UDP port 80 from security group "default" owned by you and the group
78       named "farmville" owned by user 9999999:
79
80        "udp(80..80) GRPNAME default,9999999/farmville"
