+[Vagrant](https://www.vagrantup.com/) is a easy way to setup a virtual machine (VM) to run Docker. The [Factorio Vagrant box repository](https://github.com/dtandersen/factorio-lan-vagrant) contains a sample Vagrantfile.
+
+For LAN games the VM needs an internal IP in order for clients to connect. One way to do this is with a public network. The VM uses DHCP to acquire an IP address. The VM must also forward port 34197.
 
 ```
   config.vm.network "public_network"
   config.vm.network "forwarded_port", guest: 34197, host: 34197
