# On-Premise Network

Available in VPC

This document describes the features of the On-Premise Network menu option provided in a Neurocloud Region.

## Create and delete On-Premise Networks

This section describes how to create and delete an On-Premise Network.

### Create an On-Premise Network

You can logically create an On-Premise Network that communicates with a Neurocloud VPC. To create an On-Premise Network:

1. In the VPC environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Hybrid & Private Cloud** > **Neurocloud**.
2. Navigate to **On-Premise Network > On-Premise Network**.
3. Click **[Create On-Premise Network]**.
4. When the Create On-Premise Network interface appears, enter a name and a memo, and click **[Create]**.
5. In the confirmation popup, check the information entered and click **[OK]**.
  - The created On-Premise Network is added to the On-Premise Network list.

### Delete an On-Premise Network

To delete an On-Premise Network:

              Note

              

You cannot delete an On-Premise Network that contains On-Premise Subnets. To delete an On-Premise Network, you must first delete its [On-Premise Subnets](/docs/en/neurocloud-onpremisenet-vpc#OnPremiseSubnet%EC%82%AD%EC%A0%9C).

1. In the VPC environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Hybrid & Private Cloud** > **Neurocloud**.
2. Navigate to **On-Premise Network > On-Premise Network**.
3. In the On-Premise Network list, select the On-Premise Network you want to delete and click **[Request deletion]**.
4. In the confirmation popup, check the information entered and click **[OK]**.
  - The selected On-Premise Network is deleted from the On-Premise Network list.

## Create and delete an On-Premise Subnet

This section describes how to create and delete an On-Premise Subnet.

### Create an On-Premise Subnet

You can create a subnet, which is a subdivided network segment within the On-Premise Network. The created subnet is set as a routing destination for the On-Premise Gateway. To create an On-Premise Subnet:

1. In the VPC environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Hybrid & Private Cloud** > **Neurocloud**.
2. Navigate to **On-Premise Network > On-Premise Subnet**.
3. Click **[Create On Premise Subnet]**.
4. When the Create On-Premise Subnet interface appears, enter the following information and click **[Create]**.
  - **On-Premise Network name**: Select the On-Premise Network in which you want to configure the subnet.
  - **On-Premise Subnet name**: Enter a name of the subnet you want to create.
  - **IP address range**: Enter the IP address range of the subnet you want to create.
    - The IP address range must not overlap with any existing ranges within Neurocloud.. However, the default route (0.0.0.0/0) can be configured for each On-Premise Network.
    - VPC and Subnet IP addresses are assigned by the client.
  - **Memo**: Enter a memo related to the Subnet.
5. In the confirmation popup, check the information entered and click **[OK]**.
  - The created On-Premise Subnet is added to the On-Premise Subnet list.

### Delete an On-Premise Subnet

To delete an On-Premise Subnet:

              Note

              

You cannot delete an On-Premise Subnet that has route settings configured on the On-Premise Gateway. To delete such an on-premise subnet, you must first delete the routes settings configured on the On-Premise Gateway. For more information about deleting routes, see [Delete On-Premise Gateway routes](/docs/en/neurocloud-onpremisenet-vpc#OnPremiseGatewayRoutes%EC%82%AD%EC%A0%9C).

1. In the VPC environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Hybrid & Private Cloud** > **Neurocloud**.
2. Navigate to **On-Premise Network > On-Premise Subnet**.
3. In the On-Premise Subnet list, select the On-Premise Subnet you want to delete and click **[Request deletion]**.
4. In the confirmation popup, check the information entered and click **[OK]**.
  - The selected On-Premise Subnet is deleted from the On-Premise Subnet list.

## Set On-Premise Gateway

You can learn how to create and delete an On-Premise Gateway and how to set routes for it.

### Create an On-Premise Gateway

To create an On-Premise Gateway:

              Note

              

Before creating an On-Premise Gateway, you must set up VPC and Subnet in the Neurocloud Region. Go to **Services > Networking > VPC** to create VPCs and Subnets for the Neurocloud Region. For detailed instructions, see:

- [Create a VPC](/docs/en/vpc-manage-vpc#VPC%EC%83%9D%EC%84%B1)
- [Create a Subnet](/docs/en/vpc-subnetmanage-vpc#Subnet%EC%83%9D%EC%84%B1)

1. In the VPC environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Networking** > **VPC** > **On Premise Gateway**.
2. On the On-Premise Gateway interface, click **[Create On-Premise Gateway]**.
3. When the Create On-Premise Gateway interface appears, select the VPC to which the On-Premise Gateway will belong, and click **[Create]**.
  - **On-Premise Gateway name**: Enter a unique name for the On-Premise Gateway.
  - **VPC**: Select the VPC to which the On-Premise Gateway will belong.
  - **On-Premise Subnet**: Select the Subnet on the On-Premise Network to be the destination of the created On-Premise Gateway.
  - **Memo**: Enter a memo related to the Gateway.
4. In the confirmation popup, check the information entered and click **[OK]**.
  - The created On-Premise Gateway is added to the On-Premise Gateway list.

### Set On-Premise Gateway routes

To set a route in an On-Premise Gateway: You can set routes only after an On-Premise Gateway is created. If there is no On-Premise Gateway created, see [Create an On-Premise Gateway](/docs/en/neurocloud-onpremisenet-vpc#OnPremiseGateway%EC%83%9D%EC%84%B1). If you have created an On-Premise Gateway, set the routing rules for sending and receiving traffic to and from the gateway.

#### Create On-Premise Gateway routes

To create an On-Premise Gateway route:

1. In the VPC environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Networking** > **VPC** > **On Premise Gateway**.
2. On the On-Premise Gateway list, select the On-Premise Gateway for which to set the route, and click **[Set On-Premise Gateway routes]**.
3. When the Set On-Premise Gateway interface appears, enter the source and the destination, and click **[Create]**.
  - **Source**: Enter the source IP for the On-Premise Gateway.
  - **Destination**: Select the destination for the On-Premise Gateway.
4. Check the information entered and click **[OK]**.
  - The created route is added to the list on the Set On-Premise Gateway interface.

              Note

              

To enable communication between the Neurocloud VPC and On-Premise Network, you must add routing rules to the route table. Go to **Services > Networking > VPC > Route Table** and set the communication route with the On-Premise Gateway (OGW) as the target. For detailed instructions, see:

- [Set routing rules](/docs/en/networking-vpc-vpcdetailedroutetable#%EB%9D%BC%EC%9A%B0%ED%8C%85%EA%B7%9C%EC%B9%99%EC%84%A4%EC%A0%95)

#### Delete On-Premise Gateway routes

To delete an On-Premise Gateway route:

1. In the VPC environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Networking** > **VPC** > **On Premise Gateway**.
2. On the On-Premise Gateway list, select the On-Premise Gateway route you want to delete, and click **[Set On-Premise Gateway routes]**.
3. When the Set On-Premise Gateway interface appears, click **[Delete]** to the right of the route you want to remove from the list of created routes.
4. Check that the route has been deleted from the list, and click **[OK]**.
  - The selected route is deleted from the list on the Set On-Premise Gateway interface.

### Delete an On-Premise Gateway

To delete an On-Premise Gateway:

              Note

              

You cannot delete an On-Premise Gateway if network routes are configured for it. To delete such an on-premise gateway, you must first delete all data of the routes set as the target in the on-premise gateway route settings and the route table settings. For detailed instructions, see:

- [Delete On-Premise Gateway routes](/docs/en/neurocloud-onpremisenet-vpc#OnPremiseGatewayRoutes%EC%82%AD%EC%A0%9C)
- [Delete a route table](/docs/en/networking-vpc-vpcdetailedroutetable#RouteTable%EC%82%AD%EC%A0%9C)

1. In the VPC environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Networking** > **VPC** > **On Premise Gateway**.
2. On the On-Premise Gateway list, select the On-Premise Gateway you want to delete and click **[Delete]**.
3. Once the Delete popup appears, click **[Delete]**.
  - The selected On-Premise Gateway is deleted from the On-Premise Gateway list.
