  5. Select the target NIC and security group as prompted.

    You can select multiple security groups. In such a case, the access rules of all the selected security groups apply on the ECS. To create a security group, click Create Security Group.


    Using multiple security groups may deteriorate ECS network performance. You are suggested to select no more than five security groups.

  6. Click OK.
