How to connect home DNS Server to Registra DNS server

Hi All,

I am new to DNS server (Windows 2003). I would like to
setup my own DNS server at home to host publicly in the internet some of my registered domains.
Here are what I have done:

(1) I've already registered one domain name OAKGROVE-FL.BIZ
with VoxDomain.
(2) I am using Verizon DSL line with a static IP (let
say 4.61.194.196)
(3) From VoxDomain server, I did gave OAKGROVE-FL.BIZ 2
name servers FLORIDA.OAKGROVE-FL.BIZ and SAIGON.OAKGROVE-FL.BIZ and their same IP addresses (same as above, 4.61.194.196)
(4) My server has:
- One PC name FLORIDA with LAN address 192.168.0.100 (Primary DNS)
- One PC name SAIGON with LAN address 192.168.0.101 (Secondary DNS)
- One PC name WWW with LAN address 192.0.103 (Web server)
- One router DLink DI-604 with LAN address 192.168.0.1 (Router)
- Port 80 has been opened for 192.168.0.103
- Port 53 has been opened for 192.168.0.100 (for DNS)
(5) On WWW (192.168.0.103) I already had IIS setup with some
web sites.

Note: 192.168.0.x are local addresses given by router.

From one of above 3 PCs, I can access web sites OK among these 4 units (WWW, FLORIDA,SAIGON,DI-604) Also I can ping them each other with its names and its full domain names
(i.e ping FLORIDA.OAKGROVE-FL.BIZ) From this, I can tell
that my DNS server is working (DNS server setup correctly). But it looks like working LOCALLY only. I can not access from outside of the router. For example: I can't access WWW.OAKGROVE-FL.BIZ from my workplace, but I can
access OK to FLORIDA.OAKGROVE-FL.BIZ, which is my primary DNS (has IIS with one simple web page)

What did I do wrong or what will I need?

My Server Setup:
FLORIDA.OAKGROVE-FL.BIZ = Primary DNS Server
SAIGON.OAKGROVE-FL.BIZ = Secondary DNS Server
WWW.OAKGROVE-FL.BIZ = Web Server.

I think my question should be "how can I connect my DNS to a registra (VoxDomain)'s DNS server?

Thanks you all much.

3 problems:

Your DNS server is only accessible via TCP. You need to forward UDP port 53 to your DNS server.

You cannot host 2 dns servers behind a single public IP. Shut down the 192.168.0.101 dns server.

You must use public IPs for your domains. Nobody can connect to your 192.168.x.x IPs.

Hi SilentRage,

Thanks much. I will try tonite.

Hi SilentRage,

For your 1st answer "Forward port 53..."

How can I set this up?

My router DLink DI-604 has an option to open Ports for TCP, or UDP, or both. I am not sure if this is the thing you are mentioning to. And I did opened port 53.

For the 3rd answer "Public IP"
Did you mean all IP addresses (Nameserver, Hosts, MX,...) in my DNS server have to be set up with public IPs?

Thanks much SilentRage.

You've fixed the problem with UDP port 53.

And yes, all the IP addresses for your domain needs to be changed to your public IP.

Hi SilentRage,

I follow your above instructions, but problem still. Maybe I have not done something right.

From outside (my workplace) I can access without problem to FLORIDA.OAKGROVE-FL.BIZ.
But I can not access to WWW.OAKGROVE-FL.BIZ from my workplace.

Locally (within my server - 3 PCs) I can access no problem to WWW.OAKGROVE-FL.BIZ from any of 3 PCs.

PS: FLORIDA.OAKGROVE-FL.BIZ is the PC that I am using for my own primary DNS server. WWW.OAKGROVE-FL.BIZ is another PC I am using for web server.
It looks like it can't resolve anything with AAA.OAKGROVE-FL.BIZ, except for FLORIDA.OAKGROVE-FL.BIZ or SAIGON-OAKGROVE-FL.BIZ
Again, just recalled: I did introduced 2 names
FLORIDA.OAKGROVE-FL.BIZ (& its public static IP)
SAIGON.OAKGROVE-FL.BIZ (& its public static IP)
as my name servers with VoxDomain registra.

Sorry to bother you again.

Thanks

I just tested your server and neither UDP or TCP works.

Here's the links that I use:
UDP Query TCP Query

Hi SilentRage,

It seems getting better so far. I did a few changes in the setup, and from the 2 test sites you provided, you can see some responses back. But I am not sure all are OK.
But my DNS server still can't resolve for WWW.OAKGROVE-FL.BIZ

Thanks a lot.

You still have private IPs in your zone file. 192.168.0.100 is not a proper IP for people to connect to. I told you that you need to replace them with the public IP.

OK, I did changed it to public IP. Let me check again tonight.

I also had another domain xidau.com. Using the test site, I saw only one record (SOA) being displayed, even though there is currently 6 records (2 Hosts, 2 sub-domains, 1 NS, 1 SOA) under that domain. Is the "local/Private IP" is the reason of missing some records ?

Thanks a lot SilentRage. Very helpful.

Since you don't allow zone transfers, you can't view your entire zone using DNS Crawler. This is what happens:

@4.61.234.203 xidau.com AXFR

This is all of your root domain's records. This does not include subdomains. An IP is missing for the root domain, this means people connecting to http://xidau.com doesn't get anywhere.

@4.61.234.203 xidau.com ANY

Now we're looking at the www.xidau.com IP address. Notice it is also a private IP and cannot be connected to from the internet.

@4.61.234.203 www.xidau.com A

Hi SilentRage,

Your help & answers have solved all the issues I've have for quiet a while. The DNS server works excellent.

Very Helpful SilentRage. Thanks much.
