Change network interface information​

You can change the name and description of the network interface.

  1. Go to KakaoCloud console > Networking > VPC.
  2. Click the Network Interface menu, and then select [⋮] > Change information for the target network interface.
  3. Modify the information in the pop-up window, and then click the [Save] button.

Modify security groups​

You can modify the security groups applied to the network interface.

  1. Go to KakaoCloud console > Networking > VPC.
  2. Click the Network Interface menu, and then select [⋮] > Modify security groups for the target network interface.
  3. Modify the security groups to apply to the network interface in the pop-up window, and then click the [Modify] button.

Modify allowed packet forwarding IPs​

In general, a network interface checks the source/destination IP addresses and processes packets only when they are addressed to its own IP, and does not send the remaining packets. By adding allowed packet forwarding IPs, you can configure it to send packets for the added IP addresses or IP addresses within the CIDR range.

  1. Go to KakaoCloud console > Networking > VPC.
  2. Click the Network Interface menu, and then select [⋮] > Modify allowed packet forwarding IPs for the network interface whose name you want to change.
  3. In the pop-up window, enter the IP address or CIDR you want to add. You can enter multiple values through the [Add] button.
  4. After entering the values, click the [Modify] button.
info
  • You can add up to 10 allowed packet forwarding IPs/CIDRs.

Delete network interface​

You can delete one or multiple network interfaces at the same time when they are not connected to a resource, that is, when their status is Available.

  1. Go to KakaoCloud console > Networking > VPC.
  2. Click the Network Interface menu, and then select [⋮] > Delete for the network interface whose name you want to change.
  3. Enter the delete confirmation text in the pop-up window, and then click the [Delete] button.
