[Soulwatcher]

The first thing you are going to want to do is SSH into your server. Then type the following command.

#pico -w /etc/host.conf

Scroll down until you see (order hosts,bind) Just below it type (nospoof on) and then save. It should look like this when your done

order hosts,bind
nospoof on

Thats it, your all done. Make sure to restart your network so the new rules will take effect.
