Regardless, that doesn't change my point. If you assign /31 to the
WAN, nothing will work because no matter what you put in for the
default gateway, FreeBSD will refuse to add it as its default because
it's not within the subnet of any interface. So you end up with a
firewall that can't route to the internet.
