MyDNS / DNSCache problem

[insubordinate]

Hi, Im new here. I'm gonna give it a shot (never done this before)

This is the situation.

I have 1 ip from my isp.
This is connected to:
- a Hardware Firewall (wich I can setup off course)
And on the Lan side of this firewall I have my local network.

What I need to do is this: setup a dnsserver behid that firewall.
ON this dns I need to resolve a home-domain like whateveriwant.com
But I also need to be able to visit the domain locally with the other computers.

Then I have to be albe to surf out of the network to the internet.
So my dns also has to respond to www.google.be.
I suphose by settingup their tcpIp with a specified dns

The DNS server is a virtual machine that has 2 ip's 192.168.0.23 & 192.168.0.24 /debian latest version.

I've installed mydns & dnscache like in the howto, but I'm confused about the ip settings. What Ip should be in the mydns & what ip in the dnscache?

Do I need to change anything in the resolf.conf?
What Ip's need to be in the mydns.conf
And what is up with the dnscache ip's: etc/dnscache/root/ip

Please someone help me by explaining it step by step.
tnx!
