Associate an EIP with a NAT gateway
Overview
This topic describes how to associate an elastic IP address (EIP) with a NAT gateway. After you associate an EIP with a NAT gateway, you can create DNAT and SNAT entries for the EIP.
Prerequisites
A NAT gateway is required. For details, see the CRE User Guide - Creating a NAT Gateway for step-by-step instructions.
Procedure
- On the EIP page, click the Binding Resource button in the operation column.
- On the Bind elastic public network IP to resources section, configure the parameters.
| Parameter | Description |
|---|---|
| Instance Type | Select NAT Gateway. |
| Select an instance to bind | Select the NAT gateway to be associated with the EIP. Make sure that the following requirements are met: ● You had not purchased a NAT bandwidth plan before January 26, 2018, with the Cloud account to which the NAT gateway belongs. If you did, associate the NAT bandwidth plan with the NAT gateway. ● The NAT gateway and EIP must be deployed in the same region. ● You can associate a NAT gateway with at most 20 EIPs, among which at most 10 pay-by-data-transfer EIPs can be associated. If you want to associate more EIPs, submit a ticket to request a quota increase. |
3. On the Bind elastic public network IP to resources section, click the OK button.
4. Once the IP address is successfully bound, its status has been updated to Bind.
