1. API Description

Domain name for API request: lighthouse.tencentcloudapi.com.

This API is used to delete a firewall rule of an instance.

• FirewallVersion is used to specify the version of the firewall to be manipulated. If the FirewallVersion value passed in is not equal to the current latest version of the firewall, a failure will be returned. If FirewallVersion is not passed in, the specified rule will be deleted directly.

In the FirewallRules parameter:

• Valid values of the Protocol field include TCP, UDP, ICMP, and ALL.
• For the Port field, you can enter only ALL, a single port number, several port numbers separated by commas, or a port range indicated by two port numbers separated by a minus sign. If Port is a range, the port number on the left of the minus sign must be smaller than the one on the right. If Protocol is not TCP or UDP, Port can only be empty or ALL. The length of the Port field cannot exceed 64 characters.
• For the CidrBlock field, you can enter any string that conforms to the CIDR format standard. Multi-Tenant network isolation rules take precedence over private network rules in the firewall.
• For the Action field, you can enter only ACCEPT or DROP.
• The length of the FirewallRuleDescription field cannot exceed 64 characters.

A maximum of 10 requests can be initiated per second for this API.
