Checking Whether There Is a Route Pointing to the Current NAT Gateway Check whether there is a route pointing to the public NAT gateway in the route table associated with the VPC where the public NAT gateway is located.
Notes and Constraints Public NAT Gateway When using a public NAT gateway, note the following: Common restrictions Rules on one public NAT gateway can use the same EIP, but rules on different NAT gateways must use different EIPs.
K-O N NAT Gateway NAT gateways provide the network address translation (NAT) function with 10 Gbit/s bandwidth for servers in a Virtual Private Cloud (VPC), such as Elastic Cloud Servers (ECSs), Bare Metal Servers (BMSs), and Workspace desktops, or servers that connect to a VPC through
You can create a DNAT rule only when status of the NAT gateway is ACTIVE and admin_state_up of the NAT gateway administrator is True. URI POST /v2.0/snat_rules Request Table 1 lists the request parameter.
You can create a DNAT rule only when status of the NAT gateway is ACTIVE and admin_state_up of the NAT gateway administrator is True. Specify either port_id or private_ip at a time.

In a public NAT gateway, DNAT enables servers in a VPC to share an EIP to provide services accessible from the Internet through IP address mapping or port mapping. For details, see Adding a DNAT Rule.
Public NAT gateways support pay-per-use billing by day only. Private NAT gateways support pay-per-use billing by hour only. This section describes the billing rules for pay-per-use NAT gateways.
Public NAT gateways: Besides requiring services provided by the system, some ECSs also need to access the Internet to obtain information or download software.
Scenarios This section describes how to view NAT Gateway metrics. Procedure Log in to the management console. In the upper left corner, select the target region. Under Management & Governance, select Cloud Eye.
