Managing Outbound Endpoints

Scenarios

To allow cloud servers to access an on-premises domain name, you need to create an outbound endpoint and configure endpoint rules to specify the on-premises domain name to be accessed and the IP addresses of the on-premises DNS servers. Private DNS then forwards the DNS queries for the on-premises domain name to the on-premises DNS servers based on the endpoint rules.

Process for Configuring an Outbound Endpoint

Figure 1 shows how you can configure an outbound endpoint to forward DNS queries for an on-premises domain name to the on-premises DNS servers.

Figure 1 Configuring an outbound endpoint

Creating an Outbound Endpoint

1. Log in to the management console.
2. In the service list, choose Network > Domain Name Service.

   The DNS console is displayed.

3. In the navigation pane on the left, choose Resolvers.

   The Resolvers page is displayed.

4. Click in the upper left corner and select the desired region and project.
5. In the upper right corner of the page, click Create Endpoint.
6. Configure the parameters based on Table 1.

   Table 1 Parameters for creating an outbound endpoint

   Parameter	Description	Example Value
   Endpoint Type	Type of the endpoint. There are two options: Inbound and Outbound. Select Outbound.	Outbound
   Endpoint Name	Name of the endpoint. The name can: Contain only letters, digits, underscores (_), hyphens (-), and periods (.). Contain 1 to 64 characters.	outbound-test01
   Region	Region where the outbound endpoint works.	eu-de
   VPC	The VPC over which all outbound DNS requires are forwarded to the IP addresses specified in the endpoint rules. CAUTION: The VPC cannot be changed after an endpoint is created.	vpc-test
   Subnet	The subnet must have available IP addresses. Only IPv4 addresses are supported.	Subnet-test(192.168.0.0/24)
   IP Address	There are two options: Automatically assign or Specify. To improve reliability, you need to specify at least two IP addresses, with each in a different AZ. You can optionally add up to six IP addresses.	Automatically assign

7. Click Create Now.

After an outbound endpoint is created, you need to configure endpoint rules. For details, see Modifying an Outbound Endpoint or Adding an Endpoint Rule.

Viewing an Outbound Endpoint

1. Log in to the management console.
2. In the service list, choose Network > Domain Name Service.

   The DNS console is displayed.

3. In the navigation pane on the left, choose Resolvers.

   The Resolvers page is displayed.

4. Click in the upper left corner and select the desired region and project.
5. On the Outbound Endpoints tab, locate the outbound endpoint you want to view.
6. Click the name of the outbound endpoint and view its details, such as basic configuration, IP addresses, and endpoint rules.

Modifying an Outbound Endpoint

1. Log in to the management console.
2. In the service list, choose Network > Domain Name Service.

   The DNS console is displayed.

3. In the navigation pane on the left, choose Resolvers.

   The Resolvers page is displayed.

4. Click in the upper left corner and select the desired region and project.
5. On the Outbound Endpoints tab, locate the outbound endpoint you want to modify.
6. Click Modify in the Operation column.

   You can change the endpoint name, add or delete IP addresses, and add or delete endpoint rules.

Deleting an Outbound Endpoint

1. Log in to the management console.
2. In the service list, choose Network > Domain Name Service.

   The DNS console is displayed.

3. In the navigation pane on the left, choose Resolvers.

   The Resolvers page is displayed.

4. Click in the upper left corner and select the desired region and project.
5. On the Outbound Endpoints tab, locate the outbound endpoint you want to delete.
6. Click Delete in the Operation column.
7. Confirm the outbound endpoint and click Yes.
