to Vagrant

Hi All,

I have WSL v2 Ubuntu 20.04, Host OS is Windows 10 (Version 2004 (OS Build 19041.572)). I have setup a Linux Vagrant box (ubuntu/focal64), VirtualBox as the provider, on my machine and mapped port 2222 of my host to 22 of the guest Linux box. I have not added any new interfaces and I am using the default NAT networking. Vagrant up returns error: Warning: Connection refused. Retrying..... I can't ssh into the Vagrant box by ssh vag...@127.0.0.1 -p 2222 from the host machine.

Host OS: Windows 10 (Version 2004 (OS Build 19041.572))

Guest OS: WSL v2 Ubuntu 20.04

VirtualBox: v 6.1

Vagrant: v 2.2.10

Vagrantfile:

Vagrant.configure("2") do |config|
   config.vm.box = "ubuntu/trusty64"

   config.vm.synced_folder ".", "/vagrant", disabled: true

   config.vm.provider "virtualbox" do |vb|
   vb.memory = "4024"
   vb.cpus = "1"
   end

   config.vm.provision "ansible" do |ansible|
   ansible.become = true
   ansible.verbose = "v"
   ansible.playbook = "roles/firewall.yml"
   ansible.galaxy_roles_path = "./roles"

   end
end
