(sorry for the delay in replying)
One thing you want to make sure you have off is the reverse dns lookup
setting in your httpd.conf - it's rather useless and it will add a
dependency on DNS to your web services.

Is your NAT properly configured?

what do you mean by this? the fact that #400 is working doesnt mean that
#401 will :) (there's nothing particularly wrong with #401..just saying
you are making the wrong assumption)

hmm .. why would named.conf look into /etc/hosts ?
If this is your main DNS server for your zone, then make sure that it's
properly delegated, that all the relevant hosts are defined IN YOUR BIND
config , (well, /etc/hosts can't hurt, but you are just adding extra
variables that can muddle things up).
There's lots of good docs on BIND out there. If you want a rather easy
UI, why not install webmin from the ports?
