4. Example

Example1 Adding inbound and outbound rules to a network ACL

This example shows you how to delete an inbound rule. You need to pass in only the parameters of rules that you want to retain instead of specifying the rule to be deleted. For example, the instance acl-12345678 has 2 inbound rules:

• Rule 1: TCP 192.168.1.0/24 80 Accept
• Rule 2: TCP 192.168.1.0/24 443 Accept
  
  To delete Rule 2, specify the parameters as follows.

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
&NetworkAclEntrySet.Ingress.0.Description=test
&NetworkAclEntrySet.Egress.0.Protocol=TCP
&NetworkAclEntrySet.Egress.0.Port=80
&NetworkAclEntrySet.Egress.0.CidrBlock=192.168.1.0/24
&NetworkAclEntrySet.Egress.0.Action=Accept
&NetworkAclEntrySet.Egress.0.Description=test
&<Common request parameters>

Output Example

{
  "Response": {
    "RequestId": "f23d1450-ed00-4442-98d4-be409e625e6c"
  }
}

Example2 Adding only inbound rules to a network ACL

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
&NetworkAclEntrySet.Ingress.0.Description=test
&NetworkAclEntrySet.Ingress.1.Protocol=TCP
&NetworkAclEntrySet.Ingress.1.Port=442
&NetworkAclEntrySet.Ingress.1.CidrBlock=192.168.1.0/24
&NetworkAclEntrySet.Ingress.1.Action=Accept
&NetworkAclEntrySet.Ingress.1.Description=test
&<Common request parameters>

Output Example

{
  "Response": {
    "RequestId": "f23d1450-ed00-4442-98d4-be409e625e6c"
  }
}

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
&NetworkAclEntrySet.Ingress.0.Description=test
&<Common request parameters>

Output Example

{
  "Response": {
    "RequestId": "f23d1450-ed00-4442-98d4-be409e625e6c"
  }
}
