freebsd vagrant does not connect

On arch I run:

$ vagrant init generic/freebsd12
$ vagrant up

Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.

If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.

If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.

If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.

@pmatos you could be facing this issue hashicorp/vagrant#10730 where certain versions of OpenSSH have trouble connecting via NAT. The solution seems to be adding ssh_info_public=true to your Vagrantfile or you can use the VirtualBox GUI to access the box console, and add IPQoS lowdelay throughput to /etc/ssh/sshd_config and restart OpenSSH (or reboot the box). Let me know if that fixes it.

That seems to work. Thanks!
