vm instance not setting up default to Bridged mode when using vagrant on Windows

Question

I have tried to follow this thread: Vagrant how to set network type so that its attached to bridge adapter on Virtual Box with similar problem but no success.

Also tried this: How to automatically select bridged network interfaces in Vagrant?

and Vagrant docs https://www.vagrantup.com/docs/providers/virtualbox/configuration are Linux specific.

This is my vagrant file.

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


Vagrant.configure("2") do |config|

  config.vm.box = "xoan/proxmox-ve_6.4"
  config.vm.box_version = "1.0.0"

  config.vm.network "forwarded_port", guest: 8006, host: 8006

  # Create a public network, which generally matched to bridged network.
  # Bridged networks make the machine appear as another physical device on
  # your network.
  config.vm.network "public_network", auto_config: false, Bridged: 'Realtek PCIe GbE Family Controller #5',  ip: "192.168.56.2",
    nic_type: "virtio"

  config.vm.provider "virtualbox" do |vb|
    # Display the VirtualBox GUI when booting the machine
    vb.gui = true
  
    # Customize the amount of memory on the VM:
    vb.memory = 2048
    vb.cpus = "2"
    vb.name = "proxmox1"
  end
end

I am specifying the NAT to bridged mode and giving it the Ethernet card name as VirtualBox sees it. (specifying the name since I have multiple nic interfaces)

Bringing machine 'default' up with 'virtualbox' provider...
==> default: Importing base box 'xoan/proxmox-ve_6.4'...
==> default: Matching MAC address for NAT networking...
==> default: Checking if box 'xoan/proxmox-ve_6.4' version '1.0' is up to date...
==> default: Setting the name of the VM: proxmox1
==> default: Clearing any previously set network interfaces...
==> default: Preparing network interfaces based on configuration...
    default: Adapter 1: nat
    default: Adapter 2: bridged
==> default: Forwarding ports...
    default: 8006 (guest) => 8006 (host) (adapter 1)
    default: 22 (guest) => 2222 (host) (adapter 1)
==> default: Running 'pre-boot' VM customizations...
==> default: Booting VM...
==> default: Waiting for machine to boot. This may take a few minutes...
    default: SSH address: 127.0.0.1:2222
    default: SSH username: vagrant
    default: SSH auth method: private key
    default:
    default: Vagrant insecure key detected. Vagrant will automatically replace
    default: this with a newly generated keypair for better security.
    default:
    default: Inserting generated public key within guest...
    default: Removing insecure key from the guest if it's present...
    default: Key inserted! Disconnecting and reconnecting using new SSH key...
==> default: Machine booted and ready!
==> default: Checking for guest additions in VM...
==> default: Mounting shared folders...

but everytime I run vagrant up I keep getting NAT 1 as default

Port forwarded to 127.0.0.1 are to the correct NAT, you should try to ping the ip 192.168.56.2 from your host machine. You you should be able to ssh this ip using the pivate key i.e.

ssh -i private_key 192.168.56.2
