Allow two or more vagrant VMs to communicate on their own network

Question

I want to create multiple servers that can communicate directly with each other without using public IPs. They\'ll still need internet access but nothing from outside the networ

Answer 1

Here's an example which creates two VMs:

• alpha 10.0.0.10
• beta 10.0.0.11

From inside either VM you can reach the other by IP address, and can connect to the outside world.

Vagrantfile:

# -*- mode: ruby -*-
# vi: set ft=ruby :

# Vagrant multi-machine sample setup

Vagrant.configure("2") do |config|
  config.vm.define :alpha do |alpha|
    alpha.vm.box = "hashicorp/precise64"
    alpha.vm.network :private_network, ip: "10.0.0.10"
    alpha.vm.hostname = "alpha"
  end

  config.vm.define :beta do |beta|
    beta.vm.box = "hashicorp/precise64"
    beta.vm.network :private_network, ip: "10.0.0.11"
    beta.vm.hostname = "beta"
  end
end
