Use AuthorizeSecurityGroupEgress with an Amazon SDK or CLI

To add a rule that allows outbound traffic to a specific address range

This example command adds a rule that grants access to the specified address ranges on TCP port 80.

Command (Linux):

aws ec2 authorize-security-group-egress --group-id sg-1a2b3c4d --ip-permissions IpProtocol=tcp,FromPort=80,ToPort=80,IpRanges='[{CidrIp=10.0.0.0/16}]'

Command (Windows):

aws ec2 authorize-security-group-egress --group-id sg-1a2b3c4d --ip-permissions IpProtocol=tcp,FromPort=80,ToPort=80,IpRanges=[{CidrIp=10.0.0.0/16}]

To add a rule that allows outbound traffic to a specific security group

This example command adds a rule that grants access to the specified security group on TCP port 80.

Command (Linux):

aws ec2 authorize-security-group-egress --group-id sg-1a2b3c4d --ip-permissions IpProtocol=tcp,FromPort=80,ToPort=80,UserIdGroupPairs='[{GroupId=sg-4b51a32f}]'

Command (Windows):

aws ec2 authorize-security-group-egress --group-id sg-1a2b3c4d --ip-permissions IpProtocol=tcp,FromPort=80,ToPort=80,UserIdGroupPairs=[{GroupId=sg-4b51a32f}]

Example 1: This example defines an egress rule for the specified security group for EC2-VPC. The rule grants access to the specified IP address range on TCP port 80. The syntax used by this example requires PowerShell version 3 or higher.

$ip = @{ IpProtocol="tcp"; FromPort="80"; ToPort="80"; IpRanges="203.0.113.0/24" }
Grant-EC2SecurityGroupEgress -GroupId sg-12345678 -IpPermission $ip

Example 2: With PowerShell version 2, you must use New-Object to create the IpPermission object.

$ip = New-Object Amazon.EC2.Model.IpPermission
$ip.IpProtocol = "tcp"
$ip.FromPort = 80
$ip.ToPort = 80
$ip.IpRanges.Add("203.0.113.0/24")

Grant-EC2SecurityGroupEgress -GroupId sg-12345678 -IpPermission $ip

Example 3: This example grants access to the specified source security group on TCP port 80.

$ug = New-Object Amazon.EC2.Model.UserIdGroupPair
$ug.GroupId = "sg-1a2b3c4d"
$ug.UserId = "123456789012"

Grant-EC2SecurityGroupEgress -GroupId sg-12345678 -IpPermission @( @{ IpProtocol="tcp"; FromPort="80"; ToPort="80"; UserIdGroupPairs=$ug } )
