I need to configure nat adapter as second interface  
but it does not work  
node.vm.provider “virtualbox” do |vb|  
vb.name = “kubemaster0#{i}”  
vb.memory = 2048  
vb.cpus = 2  
vb.customize [‘modifyvm’, :id, ‘–nic1’, ‘intnet’, ‘–nic2’, ‘nat’]  
end  
node.vm.network :private\_network, adapter: 1, ip: IP\_NW + “#{MASTER\_IP\_START + i}”  
node.vm.network :forwarded\_port, adapter: 2, auto\_correct: false, guest: 22, host: “#{2710 + i}”

Could You please tell me, where is wrong  
Thanks in advance

Vagrant requires the first network device attached to the virtual machine to be a NAT device. As far as I know it is currently not possible to override this requirement.

It looks like you want to setup kubernetes via vagrant so I suggest that you use the second network adapter for the kubenetes network.
