VPC networks

VPC networks can be used to create virtual, isolated networks between creoline servers. A VPC network provides an isolated environment that allows resources to be logically separated from each other. This allows data traffic within the VPC to be efficiently managed and controlled.

Managing a VPC network involves the configuration of subnets, routing tables, firewall rules and other network components. It requires knowledge of network architecture, IP addressing, security and connectivity.

Manage VPC networks

Navigate to the menu item Server → Networks, to display all VPC networks.

The VPC networks created can be managed and customized here.

Create VPC network

To create a VPC network, navigate to the menu item *Server → Networks.

Once there, you can create a new VPC network by clicking on "Create network".

Examples for VPC networks:

Once you have created the VPC network, you can then view and customize it in the "Networks" list.

Remove VPC networks

You can also quickly remove VPC networks that you have created. To do this, simply navigate to VPC network → Settings and select "Remove network" to remove the VPC network.

Connect network card to a VPC network

To connect a network card to an existing VPC network, navigate to Server → Your server → Networks and create a new network card.

To connect your VPC network to a network card, select your VPC network under "Network".

Configure network card in a Linux server

After the VPC network card has been added to the server, it must be configured in the respective server. To do this, make a note of the Mac address assigned by our system to the new VPC network card.

You can use the MAC address to determine which adapter name has been assigned to the network card by the operating system. For Debian or Ubuntu-based operating systems, ens19 is often assigned.

To do this, log on to the respective server via SSH and execute the command ip a to display all available network cards.

ip a

// [...]

3: ens19: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 16:ca:8f:70:23:22 brd ff:ff:ff:ff:ff:ff:ff:ff
    altname enp0s19

Use the Mac address to determine which adapter name was assigned by the operating system.

Here: ens19

Then open the network configuration in a file editor:

nano /etc/network/interfaces

Then add the configuration of the adapter with the respective adapter name that you determined in the previous step. E.g. ens19:

# VPC Network
auto ens19
iface ens19 inet static
        address 10.20.0.1/24

Then save the changes and execute the command ifup ens19 to activate the new network card.

Repeat these steps on all servers for which you want to set up an isolated VPC network connection and assign a new IP address from the defined network range for each server.
