How to configure your vMesh private network on Linux

You will find below the steps required to configure your private network for Linux distributions (Netplan & interfaces file). Simply replicate the following setup on every VPS defined in your network. Each VPS needs its own private network IP address (e.g., 10.0.0.2, 10.0.0.3, 10.0.0.4).

Ubuntu 20.04 / 22.04 / 24.04 and Debian 11 / 12

1. Identify your network interface

ip addr

2. Edit the Netplan configuration

sudo nano /etc/netplan/01-netcfg.yaml

3. Add the following configuration

network:
  version: 2
  renderer: networkd
  ethernets:
    eth1:
      dhcp4: no
      addresses:
        - YourAssignedIP/24 # (e.g., 10.0.0.2)

4. Apply the configuration

sudo netplan apply

Debian older versions (using /etc/network/interfaces)

1. Edit the interfaces file

sudo nano /etc/network/interfaces

2. Add the following lines

auto eth1
iface eth1 inet static
  address YourAssignedIP # (e.g., 10.0.0.2)
  netmask 255.255.255.0

3. Restart the networking service

sudo systemctl restart networking

CentOS 9 Stream / AlmaLinux 8 & 9 / Rocky Linux 8.6 & 9.x

1. Navigate to the network scripts directory

cd /etc/sysconfig/network-scripts/

2. Create or edit the interface configuration file

sudo nano ifcfg-eth1

3. Add the following configuration

DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
IPADDR=YourAssignedIP # (e.g., 10.0.0.2)
NETMASK=255.255.255.0

4. Restart the network service

sudo systemctl restart NetworkManager

Additional notes

• • Firewall configuration: ensure that your firewall settings allow traffic through the private network interface.

• • No gateway required: typically, a gateway is not needed for the private network to operate.

• • Avoid conflicts: ensure the IP range you select does not overlap with other networks you are connected to.

Choosing an IP range

Testing connectivity

You can test the connection by pinging another device on the private network:

ping OtherDeviceIP # (e.g., 10.0.0.2)
