I'm experiencing DNS issues while trying to host my own DNS & webserver on my home LAN. Basically, I see proper DNS resolve on the DNS server, but not anywhere else on the LAN or public WWW.

I'll admit I've never installed BIND before, but have administered zone files, in any event please make no assumptions.

I have a LAMP server up and running on my home LAN. It's running Ubuntu 10.04 LTS.

Given that I cannot obtain a static IP from my ISP, and also don't want to pay a domain provider for DNS management, I've decided to try and install BIND9 on the server too, so that I can manage DNS myself.

I've followed the Primary Master section of this tutorial. Note: I did not add reverse DNS, as I did not think this was necessary to resolve an IP from a domain. I will do this later, once everything else is working.

As I said, I am new, and do not really know where to begin.

Here are a few tidbits:

dig @localhost

; <<>> DiG 9.7.0-P1 <<>> @localhost
; (2 servers found)
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 20700
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2

Any pointers are appreciated.

You need to publish your name server IP with your registrar.

[ ~]$ whois  | tail
Domain servers in listed order:

All these are pointing to which I guess is your home IP.

[ ~]$ host domain name pointer

If that is true, then you need to check two things:

  1. See if you've punched a hole in your incoming modem to allow DNS traffic to reach your server
  2. See if there is an ACL in the bind config that is blocking queries. This is most likely the problem since you say you can't query from the LAN either. If you see something like:

    allow-query {; };

    in your zone or global config, change them to

    allow-query { any; };
