Overview
Currently, the connection to a VPC over DC is only supported in South China (Guangzhou), North China (Beijing), East China (Shanghai, Shanghai Finance, and Nanjing), and Southwest China (Chengdu). The public cloud can already communicate with the customer's data center network over a VPC, and the client can be directly installed.
If the region you need to connect is not supported by the connection to a VPC over DC, you need to use CCN to connect the DC gateway (VPN) with the VPC. You need to purchase the DC gateway and set the connection to a VPC over DC.
Operation Guide
Step 1. Checking Whether CCN Is Required for Connection
1. Log in to the CWPP console. In the left sidebar, click Server List > Install Cloud Workload Protection agent, and view the installation guide details in the pop-up window on the right.
﻿
2. In the installation guide, for server type, click to select Non-Tencent Cloud, and for network, click to select Dedicated Line Access.
Note:
 Select the appropriate Linux or Windows operating system according to the user's operating system.
﻿
3. If you are in South China (Guangzhou), North China (Beijing), East China (Shanghai), East China (Shanghai Finance), East China (Nanjing), or Southwest China (Chengdu):
If you have a VPC connected to the non-Tencent Cloud data center network, select the VPC connected to DC and run the installation command.
If no corresponding VPC network is found to interconnect with your non-Tencent Cloud data center network, you can connect through CCN. See Step 2.
Step 2. Confirming the VPC for Connection to DC
1. If you do not have a VPC network in the South China (Guangzhou), North China (Beijing), East China (Shanghai), East China (Shanghai Finance), East China (Nanjing), and Southwest China (Chengdu) regions, log in to the  VPC  console, and click VPC to enter the VPC page.
2. On the VPC page, click the drop-down box to select the required region, and click Create to pop up the create VPC window.
﻿
3. In the create VPC window, enter the required parameters and click Confirm to complete the creation of the VPC.
Step 3: Using CCN to Interconnect the VPC with the Non-Tencent Cloud Data Center Network Connected by a DC
1. If a CCN that communicates with the non-Tencent Cloud data center already exists, add the VPC instance selected in Step 2 to the CCN.
a. Log in to the VPC console. In the left sidebar, click CCN to go to the CCN page.
b. On the CCN page, click Manage Instances> Associate Instances in the right to go to the associate instances page.
c. On the associate instances page, click Newly Added Instances to add the VPC instance selected in Step 2 to the CCN, and then click Confirm to complete the association.
2. If the CCN is not yet configured, create one.
a. Log in to the VPC console. In the left sidebar, click CCN to go to the CCN page.
b. On the CCN page, click New, and a new CCN instance pop-up window appears.
c. In the new CCN instance pop-up window, enter the required parameters and click Confirm to complete the creation of a new CCN instance.
Note
DC gateway: Select the DC gateway connected to your non-Tencent Cloud data center network.
VPC: Select the VPC instance selected in Step 2.
If an IP range conflict occurs, go back to Step 2 and select or create a new VPC instance that does not conflict.
3. Go back to the CWPP console and see Step 1 to obtain the installation command. Your non-Tencent Cloud data center needs to allow access to four ports (5574, 8080, 80, and 9080) of the IP described in Step 1.
