Vagrant is a tool for building and distributing development environments.

VagrantPlugins::ProviderVirtualBox::Driver::Base#forward_ports

Forwards a set of ports for a VM.

This will not affect any previously set forwarded ports,
so be sure to delete those if you need to.

The format of each port hash should be the following:

    {
      name: "foo",
      hostport: 8500,
      guestport: 80,
      adapter: 1,
      protocol: "tcp"
    }

Note that "adapter" and "protocol" are optional and will default
to 1 and "tcp" respectively.
