You can easily access the Internet through a NAT gateway by completing the following steps.
Note:A rental fee for one hour will be frozen upon creation of the NAT gateway.
Parameter | Description |
---|---|
Gateway name | Enter the NAT gateway name with up to 60 characters. |
Region | Select a region for the NAT gateway. |
VPC | Select a VPC for the NAT gateway. |
Gateway type | The types include:
|
Outbound bandwidth cap | The maximum outbound bandwidth cap of the NAT gateway. Valid values: 10, 20, 50, 100, 200, 500, 1000, 2000 and 5000. Unit: Mbps. |
EIP configuration | You can configure the EIPs associated with the NAT gateway using existing EIPs or by creating EIPs.
|
Note:When the public network is accessed through the EIP bound to a NAT gateway, the public network traffic is limited by the lower of the NAT gateway’s or EIP’s bandwidth cap. To ensure that the traffic peak is within the NAT gateway’s bandwidth cap and avoid packet loss, we recommend:
- When you create a NAT gateway, the outbound bandwidth cap needs to be smaller or equal to the total bandwidth caps of EIPs to be bound.
- For an existing NAT gateway that already bound with an EIP, you can modify the outbound bandwidth cap of the NAT gateway or EIP, or bind multiple EIPs, ensuring that the outbound bandwidth cap of the NAT gateway is smaller or equal tothe total bandwidth caps of bound EIPs.
After the NAT gateway is created, you need to configure routing policies to direct the subnet traffic to the NAT gateway.
If Gateway Traffic Monitoring Details is enabled, you can view the metrics of IP traffic flowing through a NAT gateway over the last 7 days, and set an outbound bandwidth of the specified NAT gateway for traffic from an IP address.
