Auto-renewing a NAT Gateway
Auto-renewal can prevent NAT gateways from being automatically deleted if you forget to manually renew them. The auto-renewal rules are as follows:
- The first auto-renewal date is based on when a NAT gateway expires and the billing cycle.
- The auto-renewal period of a NAT gateway depends on the subscription term. Monthly subscriptions renew each month, and yearly subscriptions renew each year.
- You can enable auto-renewal anytime before a NAT gateway expires. By default, the system will make the first attempt to charge your account for the renewal at 03:00 seven days before the expiry date. If this attempt fails, it will make another attempt at 03:00 every day until the subscription is renewed or expires.
- After auto-renewal is enabled, you can still renew the NAT gateway manually if you want to. After a manual renewal is complete, auto-renewal is still valid, and the renewal fee will be deducted from your account seven days before the new expiry date.
- By default, the renewal fee is deducted from your account seven days before the new expiry date. You can change this auto-renewal payment date as required.
- For more information about auto-renewal rules, see Auto-Renewal Rules.
Prerequisites
The yearly/monthly public NAT gateway is not expired.
You can enable auto-renewal in either of the following ways:
Auto-renewal has been enabled during the purchase.
You can enable auto-renewal on the NAT Gateway purchase page, as shown in Figure 1. For details, see Buying a Public NAT Gateway.
Enabling Auto-Renewal on the Renewals Page
- Log in to the management console.
- Hover over Billing & Costs in the upper part of the console and choose Renewal from the drop-down list.
The Renewals page is displayed.
- Set the search criteria.
