AuthorizeSecurityGroupIngressResponse

This example enables inbound traffic on TCP port 22 (SSH). The rule includes a description to help you identify it later.

To add a rule that allows inbound SSH traffic from an IPv4 address range

var client = new AmazonEC2Client();
var response = client.AuthorizeSecurityGroupIngress(new AuthorizeSecurityGroupIngressRequest 
{
    GroupId = "sg-903004f8",
    IpPermissions = new List<IpPermission> {
        new IpPermission {
            FromPort = 22,
            IpProtocol = "tcp",
            ToPort = 22
        }
    }
});


            

This example enables inbound traffic on TCP port 80 from the specified security group. The group must be in the same VPC or a peer VPC. Incoming traffic is allowed based on the private IP addresses of instances that are associated with the specified security group.

To add a rule that allows inbound HTTP traffic from another security group

var client = new AmazonEC2Client();
var response = client.AuthorizeSecurityGroupIngress(new AuthorizeSecurityGroupIngressRequest 
{
    GroupId = "sg-111aaa22",
    IpPermissions = new List<IpPermission> {
        new IpPermission {
            FromPort = 80,
            IpProtocol = "tcp",
            ToPort = 80,
            UserIdGroupPairs = new List<UserIdGroupPair> {
                new UserIdGroupPair {
                    Description = "HTTP access from other instances",
                    GroupId = "sg-1a2b3c4d"
                }
            }
        }
    }
});


            

This example adds an inbound rule that allows RDP traffic from the specified IPv6 address range. The rule includes a description to help you identify it later.

To add a rule that allows inbound RDP traffic from an IPv6 address range

var client = new AmazonEC2Client();
var response = client.AuthorizeSecurityGroupIngress(new AuthorizeSecurityGroupIngressRequest 
{
    GroupId = "sg-123abc12 ",
    IpPermissions = new List<IpPermission> {
        new IpPermission {
            FromPort = 3389,
            IpProtocol = "tcp",
            Ipv6Ranges = new List<Ipv6Range> {
                new Ipv6Range {
                    CidrIpv6 = "2001:db8:1234:1a00::/64",
                    Description = "RDP access from the NY office"
                }
            },
            ToPort = 3389
        }
    }
});
