| ---------------------- | ----------------------------------------------------------------------------------------------------------------------------------- |
| **Direction**          | Specifies the traffic flow for the rule. Select **Ingress** to allow incoming traffic or **Egress** to allow outgoing traffic.      |
| **Protocol**           | Select the network protocol for the rule.                                                                                           |

| **CIDR**               | Enter the IP address range in CIDR notation to which the rule applies (for example, `192.168.1.0/24` or `0.0.0.0/0`).               |

| **Maximum Port Range** | Specifies the ending port number for the rule. For a single port, enter the same value in both the minimum and maximum port fields. |
| **Description**        | Enter an optional description to help identify the purpose of the security group rule.                                              |
