BIND-8/9 interface bug? Or is it FreeBSD?

I hadn't considered jails -- I can't believe I forgot about
them. An excellent idea.
For now, I've moved both of my nameservers over to relying
entirely on the public IP network for transmission of
everything, and as expected, it works great. I might have
to try the jail method for the private network!
