# Port configuration

### AWS <a href="#aws" id="aws"></a>

* Add the rule to the security group using one of the following commands :
  1. ​[authorize-security-group-ingress](https://docs.aws.amazon.com/cli/latest/reference/ec2/authorize-security-group-ingress.html) (AWS CLI)

     ```
     aws ec2 authorize-security-group-ingress --group-id security_group_id --protocol tcp --port 32440-32449 --cidr cidr_ip_range
     ```
  2. Grant-EC2SecurityGroupIngress (AWS Tools for Windows PowerShell)

     The Grant-EC2SecurityGroupIngress command needs an IpPermission parameter, which describes the protocol, **port range**, and IP address range to be used for the security group rule. The following command creates the IpPermission parameter:

     ```
     PS C:\> $ip1 = @{ IpProtocol="tcp"; FromPort="32440"; ToPort="32449"; IpRanges="cidr_ip_range" }
     ```

     ```
     PS C:\> Grant-EC2SecurityGroupIngress -GroupId security_group_id -IpPermission @($ip1)
     ```
