option to move NAT adapter as 2nd interface (not 1st and default one)

[ReSearchITEng]

Expected behavior

For bridged (public_network), there should be an option (if not the default one) to make the NAT adaptor 2nd, and bridged adaptor the 1st one, while still being able to connect to the machine.

If we try this now:

  config.vm.network "public_network", :adapter=>1 , type: "dhcp", :bridge => "enp3s0"

Vagrant is not able to connect to the machine any longer, as it does not

not interfere with the box's networking definitions

Actual behavior

No methods for both vagrant and user to connect to the VM.

Steps to reproduce

 config.vm.network "public_network", :adapter=>1 , type: "dhcp", :bridge => "enp3s0"

Hi there,

Thanks for creating this issue. I'm going to close this as Vagrant's behavior is built to use the first adapter as the NAT adapter for communication. Changing this changes internal behavior of Vagrant, and I'm not sure that such a large modification is worth the gain of being able to rearrange the network adapters within the guest. If there are strong reasons why this should be supported, I'm very happy to consider them. Cheers!

Is it possible to use UPNP without making the bridged network the first adapter?
