OSX Server Website DNS problems

Question

I wanted to have a server  so I decided to get the mac mini server. We want to set up a small website with simple web services running on python and ruby.
Now I'm trying to set it up to have a website connected to our domain (olm.io), but the domain name doesn't forward to the mac mini server.
I believe the server is set up correctly. The router is set up to port forward incoming connections on port 80 to the server. To test that, connections to the ip 190.160.227.68 retrieves the server and shows up the test website.
I entered our ISP dns servers and also set up a dns server on the osx server.
From outside this shows from outside:
$ dig www.olm.io
; <<>> DiG 9.9.2-P1 <<>> www.olm.io
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 20417
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1
;; OPT PSEUDOSECTION:

;; SERVER: 8.8.8.8#53(8.8.8.8)
;; WHEN: Thu Jan  9 14:54:03 2014
;; MSG SIZE  rcvd: 39
From inside the network this shows up:
$ dig www.olm.io
; <<>> DiG 9.8.3-P1 <<>> www.olm.io
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 27239
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 0

www.olm.io.        10800    IN    A    192.168.0.10

;; SERVER: 127.0.0.1#53(127.0.0.1)
;; WHEN: Thu Jan  9 11:54:25 2014
;; MSG SIZE  rcvd: 58
Also checking the hostname says its ok:
$ sudo changeip -checkhostname
Primary address     = 192.168.0.10
Current HostName    = www.olm.io
DNS HostName        = www.olm.io
Ok so from the inside of our network the website shows up, and from outside when looking at the public ip of the network the website also shows up.
What I'm missing is that when anybody types www.olm.io our website appears.
At one time I tried setting up Google public dns service, just to try it, but now it seems to be stuck referring to google 8.8.8.8 server,
$ nslookup 190.160.227.68                                                                                                                                                                                                                                               
Server:         8.8.8.8
Address:        8.8.8.8#53
Non-authoritative answer:
68.227.160.190.in-addr.arpa     name = pc-68-227-160-190.cm.vtr.net.
Authoritative answers can be found from:
$ nslookup www.olm.io                                                                                                                                
Server:         8.8.8.8
Address:        8.8.8.8#53
** server can't find www.olm.io: NXDOMAIN
I believe the problem is on the domain set up, which is as follows:
Registrar
Organization Name :
NIC.io
Primary Nameserver
Name Server:
ns00.olm.io
IPv4 Address:
190.160.227.68
Secondary Nameserver
Name Server:
ns00.vtr.net
Extra Nameservers (Optional)
Name Server:
ns01.vtr.net

Thanks for the help

Answer 1

You will have two sets of DNS servers, your public DNS and the DNS running on your local network.  If your external DNS is getting to your servers, then that's probably working.  If you are getting the public IP address from your local network, then your gateway-router needs to "reflect" that address, or you'll need to configure local DNS services (OS X Server needs that in any case) to provide the local IP address for the public DNS name.
Put another way, read the article cited earlier and make sure your local DNS is correct.  You can test for most of the common network and DNS configuration errors with the following harmless, diagnostic Terminal.app command:
sudo changeip -checkhostname
...and this will tell you about the configuration, and whether no changes are required, or about the various errors that might be detected.
You can see what IP address you're getting with the following Terminal.app command:
dig +short oc.example.com
...or whatever DNS host name you're using.  You'll get either the public IP address (which if you use on the local network, your gateway-router needs to be able to detect that and run the connections back into your network) or your internal local network address.
Your local network clients will want to reference your local DNS server.
Do read the article cited earlier, too.
