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?

Is the DNS Server a local lan DNS, an internet DNS, or both?

If just internet, then your setup is fine if port forwarding is enabled on the firewall to the DNS server.

If both or just local, you will need to setup the firewall to also be a router. The ip assignments should be fine.

thanks. this will do both local and internet for my personal domain. so does my server's local address 10.1.10.2 go in the master zone file or does my router / firewall's 66.92.aaa.aaa ?
