Function

This API is used to create a security group rule.

URI

POST /v3/{project_id}/vpc/security-group-rules

**Table 1** Parameter description
Name	Mandatory	Type	Description
project_id	Yes	String	Project ID. For details about how to obtain a project ID, see Obtaining a Project ID.

Request Parameter

**Table 2** Request body parameter
Parameter	Mandatory	Type	Description
dry_run	No	Boolean	Whether to only send the check request. The value can be: true: A check request will be sent and no security group rule will be created. Check items include mandatory parameters, request format, and permission verification. If the check fails, an error will be returned. If the check succeeds, response code 202 will be returned. false (default value): A request will be sent and a security group rule will be created.
security_group_rule	Yes	CreateSecurityGroupRuleOption object	Request body for creating a security group rule.

**Table 3** CreateSecurityGroupRuleOption
Parameter	Mandatory	Type	Description
security_group_id	Yes	String	ID of the security group to which the security group rule belongs.
description	No	String	Provides supplementary information about the security group. The value can contain no more than 255 characters and cannot contain angle brackets (< or >).
direction	Yes	String	Inbound or outbound direction of a security group rule. The value can be: ingress: inbound direction egress: outbound direction
ethertype	No	String	IP version The value can be IPv4 or IPv6. If you do not set this parameter, IPv4 is used by default.
protocol	No	String	Protocol type The value can be icmp, tcp, udp, icmpv6 or an IP number (0 to 255). Constraints: If the parameter is left blank, all protocols are supported. When the protocol is icmpv6, IP version should be IPv6. When the protocol is icmp, IP version should be IPv4.
multiport	No	String	Port or port range The value can be a single port (80), a port range (1-30), or inconsecutive ports separated by commas (22,3389,80). The port is from 1 to 65535.
remote_ip_prefix	No	String	Remote IP address. If direction is set to egress, the parameter specifies the source IP address. If direction is set to ingress, the parameter specifies the destination IP address. The value is an IP address or a CIDR block. Constraints: The parameter is mutually exclusive with parameters remote_group_id and remote_address_group_id. If this parameter is left blank, the remote IP address is not limited, and the traffic from all remote IP addresses is allowed or rejected.
remote_group_id	No	String	ID of the remote security group, which allows or denies traffic to and from the security group. Value range: ID of an existing security group The parameter is mutually exclusive with parameters remote_ip_prefix and remote_address_group_id.
remote_address_group_id	No	String	ID of the remote IP address group. Value range: ID of an existing IP address group The parameter is mutually exclusive with parameters remote_ip_prefix and remote_group_id.
action	No	String	Action of the security group rule. The value can be: allow deny The default value is allow.
priority	No	String	Rule priority in a security group. The value is from 1 to 100. The value 1 indicates the highest priority. The default value is 1.

Example Request

Create an inbound rule in the security group whose ID is 1c8d9f94-6022-4518-bb98-e0145fcc7b33.
