You need to create a public NAT gateway in Subnet-NAT and configure an SNAT rule for Subnet-A01. The system automatically adds a route pointing to the NAT gateway to the route table of VPC-A.

(Optional) Deleting a NAT gateway: Click Delete >>. In the NAT gateway list, locate the NAT gateway to delete, and click Delete in the Operation column. If you want to perform this operation, enter DELETE or click Auto Enter. Click OK.
Checking whether the network configuration is correct Check whether the network configuration is correct by referring to Public NAT Gateway Troubleshooting. If the network configuration is correct, go to 6.

NAT Gateway: Public NAT gateways translate private IP addresses into EIPs, and are used by cloud servers in a VPC for secure, cost-effective Internet access.
SNAT Protection Overview Context The CFW standard edition protects traffic between EIPs, for example, traffic generated when the Network Address Translation (NAT) gateway is used for multiple VPCs or subnets to use EIPs to initiate external access.
The actual pricing is subject to that settled on the NAT Gateway console. We suggest that you delete private NAT gateways that are no longer needed to avoid charges. For more information about private NAT gateways, click here.
To obtain a corresponding IPv6 EIP, enable the IPv6 EIP function. 1 NAT gateway NAT-Test This public NAT gateway will have an EIP bound. 1 VPN gateway VPN-GW-Test This VPN gateway is an egress gateway in a VPC and allows reliable and encrypted communications between a VPC and an on-premises
Procedure for creating a public NAT gateway: In the left navigation pane of the management console, choose Network > NAT Gateway to go to the NAT Gateway console. Then click Buy Public NAT Gateway.

Instead, you are advised to configure a public network NAT gateway to use SNAT for flexible management.

NAT Gateway NAT Gateway provides public and private NAT gateways. A public NAT gateway provides SNAT and DNAT to let cloud servers in a VPC use an EIP to communicate with the Internet. CFW protects the NAT gateway traffic by protecting the VPC where the NAT gateway resides.
For public and private NAT gateways, DNAT rules can be modified. Parent topic: DNAT Rules
The VPC is being used by ELB (either dedicated or shared load balancers), NAT Gateway, VPC Endpoint, or DCS.
NAT Gateway is easier to configure and use than SNAT. This service can be flexibly deployed across subnets and AZs and has different NAT gateway specifications. You can click NAT Gateway under Networking on the management console to try this service.
This public IP address can be statically configured, or translated through NAT in NAT traversal scenarios (your device is deployed behind a NAT gateway).

NAT Gateway: provides both public and private NAT gateways. A public NAT gateway provides SNAT and DNAT to let cloud servers in a VPC share an EIP to communicate with the Internet.
