REPOSTED DNS Server for home office with firewall


setting up a dns server on a redhat 7.3 box in the dmz of my home office network (see network layout below).

QUESTION 1.
I am setting Up the Master Zone File. i have two static IP addresses: 66.92.aaa.aaa. and 66.92.bbb.bbb. my dsl connection is shared through my linux firewall / router. What IP address should go in my file for the network setup as illustrated below?
a. 66.92.aaa.aaa
b. 66.92.bbb.bbb
c. 10.1.10.2
d. none of the above (please specify)

QUESTION 2
Do I have to reassign or alias an IP address on my firewall to make this work and if so which ones and what addresses should they get?
.___________________

Three components of office network
A. FIREWALL with three NIC's
eth2 IP Address: 66.92.aaa.aaa (connection to the internet)
eth1 IP Address: 10.1.10.1 (connection to DNS server only)
eth0 IP Address: 10.1.1.1 (connection to local network)

B. DNS SERVER
eth0 IP Address: 10.1.10.2

C. WORKSTATION
eth0 IP Address: 10.1.1.2

perhaps my question isn't clear

when i make the first entry in my master zone file for my ip address, do i use the local network address (10.1.10.2) of the linux box that will run my dns / named software from behind the router / firewall or do i use the real internet address of the router firewall (66.92.aaa.aaa)?

The idea of a dns server is to convert names into numbers and to validate names from numbers, for servers you have locally.
The outside world needs to know how to find your dns server too, eg from domain records etc...
If all you want is faster lookups, a caching nameserver is the idea...
and your smoothie has one already...
Have you read this how to? http://tldp.org/HOWTO/DNS-HOWTO.html

yup and i bought his book, too. i'm not tryig to make a caching name server but an actual dns for a personal domain. i really like his conceptual introduction using nonrecursive requests but i'd like to recommend a more cook book approach when it comes to the file editing with a cross reference to his more conceptual explanations. i'm going to break down and buy dns & bind (the cricket book) i understand the concepts (i think) but i'm getting bogged down in how the file entries relate to each other. i'll give this a try and see if i can't post back more specific questions about the file.
