4. Example

Example1 Adding inbound and outbound rules to a network ACL

This example shows you how to modify network ACL rules by only passing in the rule you want to retain and discarding the ones you want to delete. For example, the acl-12345678 has two inbound rules:

• Rule 1: TCP 192.168.1.0/24 80 Accept
• Rule 2: TCP 192.168.1.0/24 443 Accept
  
  If you want to delete the inbound rule 2, pass in parameters shown in the example.

Example3 Deleting inbound rules of a network ACL

This example shows you how to modify network ACL rules by only passing in the rule you want to retain and discarding the ones you want to delete. For example, the acl-12345678 has two inbound rules:

• Rule 1: TCP 192.168.1.0/24 80 Accept
• Rule 2: TCP 192.168.1.0/24 443 Accept
  
  If you want to delete the inbound rule 2, pass in parameters shown in the example.

Input Example

https://vpc.tencentcloudapi.com/?Action=ModifyNetworkAclEntries
&Version=2017-03-12
&NetworkAclId=acl-12345678
&NetworkAclEntrySet.Ingress.0.Protocol=TCP
&NetworkAclEntrySet.Ingress.0.Port=80
&NetworkAclEntrySet.Ingress.0.CidrBlock=192.168.1.0/24
&NetworkAclEntrySet.Ingress.0.Action=Accept
