Setting Up and Configuring a Private Network

This document provides a step-by-step guide to creating a private network in the cloud control panel and configuring it on the operating system.

Step 1: Creating a Private Network in the Cloud Control Panel​

To set up a private network, follow these steps in the cloud control panel:

  1. Log in to the Control Panel:

    • Sign in to your account and navigate to the Cloud Server section in the control panel.

  2. Access the Networks Section:

    • From the main menu, select Network.

  3. Create a New Network:

    • Click on Private Network. network1
    • Select Create Network. network2

  4. Configure Network Settings:

    • IP Address:
      • Value: 192.168.1.1/16
      • Explanation: This is the base network address with a /16 mask, allowing for 65,534 usable IP addresses.
    • Network Name:
      • Enter a custom name, e.g., private-net-01.
    • Gateway:
      • Enabling this option allows servers within the network to connect to the internet or other networks through the gateway. If disabled, the network will be fully isolated.
      • If using a device (e.g., a router) as a gateway, enter its address here.
    • DHCP:
      • Enabling DHCP allows automatic IP address assignment. If disabled, you must manually assign IP addresses on your servers.
      • If no range is specified, addresses will be assigned automatically.
    • DNS:

      • Enter preferred DNS servers, e.g., 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).

  5. Save and Create the Network:

    • Click Create Network to finalize the setup.

  6. Attach the Network to a Cloud Server:

    • Select the created network and click Attach to Server. network4

    • In the pop-up window, select the desired server from the list, click Confirm, and wait for the settings to apply. network5

Step 2: Configuring the Network on Linux​

After creating the private network, you need to configure the operating system to use it.

1. Identify the Network Interface​

First, find the network interface associated with the private network:

# For Ubuntu, Debian, RockyLinux, AlmaLinux
ip a

# For FreeBSD
ifconfig -a
  • Note down the interface name (e.g., ens6).

2. Edit the Network Configuration File​

Modify the network configuration file based on your operating system:

echo "network:
  version: 2
  ethernets:
    ens6:
      dhcp4: true
    match:
       macaddress: 'fa:16:3e:fd:93:7c'" | sudo tee /etc/netplan/90-vpc.yaml
sudo chmod 600 -R /etc/netplan/

3. Apply the Changes​

Apply the configuration using the following commands:

sudo netplan apply

4. Verify the Configuration​

Check the configuration using:

# For Ubuntu, Debian, RockyLinux, AlmaLinux
ip r

# For FreeBSD
ifconfig -a
tip
  • If using a static IP instead of DHCP, change dhcp4: true to dhcp4: false and manually enter the IP address, gateway, and DNS in the configuration file.
  • Ensure that the network interface name (e.g., ens6) matches the output of ip a or ifconfig -a.
