DNS inside a firewall

[dave at dpallan.com (David Allan)]

You shouldn't need to forward a port to it just to cname other people's
boxes.  Forwarding the port will allow the outside world to access it,
which may be something else you want to do, but I would argue is probably
a bad thing, given BIND's security record. (I speak here from personal
experience.)  Just my $.02.
