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.
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.
For details, see Buying a Public NAT Gateway. For public NAT gateway planning, see Table 7. Parent topic: Creating Resources
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.

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.
Creating an Enterprise Router Scenarios This section describes how to create an enterprise router. Procedure Create an enterprise router in region A. For details, see Creating an Enterprise Router. For enterprise router details, see Table 6. Parent topic: Creating Resources
Creating VPC Attachments for the Enterprise Router Scenarios This section describes how to attach VPCs to the enterprise router and configure routes for the VPCs and enterprise router. Procedure Attach the four VPCs to the enterprise router. For details, see Creating VPC Attachments
The VPC is being used by ELB (either dedicated or shared load balancers), NAT Gateway, VPC Endpoint, or DCS. For more constraints on using enterprise router, see Notes and Constraints.
