The editor will share with you the method of cloning the security group after changing the network type of the security group to a proprietary network. I hope you will gain a lot after reading this article. Let's discuss it together.

Clone security group

Aliyun allows you to clone security groups across regions and network types.

Application scenario

You may need to clone a security group in the following scenarios:

Suppose you have created a security group SG1 in region A, and you need to use exactly the same rules as SG1 for the instances in region B. you can directly clone SG1 to region B instead of creating a security group from scratch in region B.

Suppose you have created a security group SG2 for classic network, and you need to use exactly the same rules as SG2 for some instances in VPC network. You can change the network type to VPC when you clone SG2 to generate a security group for VPC network.

If you need to implement new security group rules for an online business, you can first clone the original security group as a backup, and then modify the rules in the security group. If the new security group rules adversely affect your online business, you can restore the security group rules in whole or in part.

prerequisite

If you need to change the network type of the security group to a private network (VPC), you should have created at least one private network in the destination region.

Operation steps

Log in to the ECS console of the CVM.

In the left navigation bar, click Security Group.

Select the region.

"in the list of security groups, locate the security group that you want to clone, and in the actions column, click Clone."

In the Clone dialog box, set the information for the new security group:

Destination region: select the region where the new security group applies. At present, all regions are not supported. The supported regions are displayed on the console.

Security group name: sets the name of the new security group.

Network type: select the network type that the new security group applies to. If you choose a private network, you also need to select an available private network in the destination region.

Click OK after confirming that it is correct.

When created successfully, the clone dialog box closes automatically. You can see the cloned new security group in the list of security groups.

After reading this article, I believe you have a certain understanding of the method of cloning security groups after changing the network type of security groups to proprietary networks.
