Is the host running a DNS service? If it is, it should respond pretty quickly for a nonexistent hostname query. Why doesn't it? If it is not running a DNS service, how did you arrive at this decision to point to the host? You may want to run tcpdump on the host and at the same time on a linux VM and see what happens. You can do the same thing for a freebsd VM to try to narrow down where the problem lies.
