You can change the Virtual Server’s IP and add a network port to the Virtual Server to configure the IP.

Change IP

You can change the IP of the Virtual Server.

Caution
  • If you proceed with changing the IP, you will no longer be able to communicate using that IP, and you cannot cancel the IP change while it is in progress.
  • The server is rebooted to apply the changed IP.
  • If the server is running the Load Balancer service, you must delete the old IP from the LB server group and directly add the updated IP as a member of the LB server group.
  • Servers using Public NAT/Private NAT must disable and reconfigure Public NAT/Private NAT after an IP change.
    • If you are using Public NAT/Private NAT, first disable the use of Public NAT/Private NAT, complete the IP change, and then set it up again.
    • Whether to use Public NAT/Private NAT can be changed by clicking the Edit button of Public NAT IP/Private NAT IP on the Virtual Server Details page.

To change the IP, follow the steps below.

  1. Click the All Services > Compute > Virtual Server menu. Navigate to the Service Home page of Virtual Server.
  2. On the Service Home page, click the Virtual Server menu. You will be taken to the Virtual Server List page.
  3. On the Virtual Server List page, click the resource whose IP you want to change. You will be taken to the Virtual Server Details page.
  4. On the Virtual Server Details page, click the Edit button for the IP entry you want to modify. IP Edit popup window opens.
  5. IP Edit In the popup window, after selecting Subnet, set the IP to be changed.

  6. When the setup is complete, click the Confirm button.
  7. When the popup notifying IP modification opens, click the Confirm button.

Configure the server’s IP after adding a network port

If you created a Virtual Server with Ubuntu Linux, after adding a network port in Samsung Cloud Platform, you also need to configure the IP on the server.

  1. Log in as the root user on the virtual server’s OS and use the ip command to verify the assigned network interface name.
