Allowing VPCs to Share an EIP to Access the Internet Using Enterprise Router and NAT Gateway Overview Network and Resource Planning Creating Resources Configuring Networks Verifying Network Connectivity
One of the VPCs will be used to host a NAT gateway Assign an EIP and create a public NAT gateway in VPC 4. 3 Configuring Networks Create VPC attachments for the enterprise router: Attach the four VPCs to the enterprise router.
The VPC is being used by ELB (either dedicated or shared load balancers), NAT Gateway, VPC Endpoint, or DCS.
If a service VPC is being used by ELB, VPC Endpoint, NAT Gateway (private NAT gateway), Distributed Cache Service (DCS), or hybrid DNS, this VPC cannot be attached to an enterprise router. For details about constraints on enterprise routers, see Notes and Constraints.

Enterprise routers can be used with Direct Connect, Cloud Connect, and NAT Gateway to construct different networks. For details, see Enterprise Router Best Practices.
NAT gateway: a route configured by the system for routing traffic from the VPC subnet to the NAT gateway. NAT gateway Create a public NAT gateway in VPC 4, and add an SNAT rule with an EIP associated.
Assigning an EIP and Creating a Public NAT Gateway Scenarios This section describes how to assign an EIP and create a public NAT gateway. Procedure Assign an EIP in region A. For details, see Assigning an EIP. Create a public NAT gateway in region A.
Adding an SNAT Rule to the NAT Gateway Scenarios This section describes how to add an SNAT rule to the public NAT gateway. Procedure Add an SNAT rule to the public NAT gateway. For details, see Adding an SNAT Rule. For SNAT rule details, see Table 7.
ELB, NAT Gateway, VPC Endpoint and DCS are deployed in the VPC. Refer to solution 1 or solution 2. When method 2 is used, if a VPC wants to access public network, the traffic from the VPC is forwarded to the enterprise router and then to the public network.
Access to the public network from the cloud network Allowing VPCs to Share an EIP to Access the Internet Using Enterprise Router and NAT Gateway Enterprise Router NAT Gateway Elastic IP VPC ECS There are four VPCs in region A on Huawei Cloud.
Locate the target virtual gateway and click Delete in the Operation column. A confirmation dialog box is displayed. Click OK. A deleted virtual gateway cannot be recovered. Parent topic: Virtual Gateway Attachments
The VPC is being used by ELB (either dedicated or shared load balancers), NAT Gateway, VPC Endpoint, or DCS. Suggestion 1: Change the destination address of the route.
The VPC is being used by ELB (either dedicated or shared load balancers), NAT Gateway, VPC Endpoint, or DCS.
The VPC is being used by ELB (either dedicated or shared load balancers), NAT Gateway, VPC Endpoint, and DCS. Create a VPC peering connection between the service VPC and transit VPC.
