Networking, DNS behind router with bind9

What kind of problem are you facing ??

You would not able to do reverse dns internaly, you will have to tell your ISP to do reverse dns for your public ip

I dont really care about reverse dns, I can't do it with my isp,

Basically tell me how to setup my dns (same box as webserver ) so that when I go to example.com (my domain) resolves to my server on my internal network.

I need to access this domain from home and from the outside world.

I'd like the flexibility to setup subdomain,extra domains, thats why I just didn't set up an A record entry at my registrar for the domain.

Thanks!

Ok

From Domain Control panel
have you change your Name server already ??
which should be

ns1.example.com
ns2.exmaple.com

which should be point to your public ip address

yes my registrar has the nameservers changed to ns1.example.com/ns2.example.com.

Those point to my public ip.  The router is set to forward that traffic to my dns server on port 53 tcp/udp

ok have a look at my zone file

$TTL 14400
@ 86400   IN      SOA     ns1.xxx.co.uk. ns2.xxxx.co.uk. (
                2008021501      ; serial
                86400           ; refresh
                7200            ; retry
                3600000         ; expire
                86400 )         ; minimum

                        IN NS ns1.xxx.co.uk.
                        IN NS ns2.xxx.co.uk.
                        IN MX 10  mail.xxxx.co.uk.
                        IN A 11.11.11.11
ns1                     IN A 11.11.11.11
ns2                     IN A 22.22.22.22
www                     IN A 11.11.11.11
mail                    IN A 11.11.11.11


now come to named.conf

have you allowed to do Dns query in your named.conf ??

options {
        listen-on port 53 { 11.11.11.11; 22.22.22.22; 127.0.0.1; };
        listen-on-v6 port 53 { ::1; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";

        // Those options should be used carefully because they disable port
        // randomization
        // query-source    port 53;
        // query-source-v6 port 53;

        allow-query     { any; };
        Recursion no;
};

other wise Dns query will not work

if you Edit your named.conf file with those options

then dns should work

also , have you opended port 53 in your linux server ??

can you telnet the pc internal

telnet pc ip 53 ??

also from out side of your network , telnet yourpublic ip 53

what are the 11.11.11 / 22.22..... addresses? local ip's or external, my whole problem has been figuring out what local and external values go where.

Thanks

Also, yes I can telnet from inside and outside the network on port 53

it whould be internal

try with

  listen-on port 53 { ANY; };

One more thing

in your Zone config

you put public ip I gueess

Since your dns server is internal so you need to put the ip address of Internal  pc

according to your configuraiton
www              IN      A       PU.BL.IC.IP
mta              IN      A       PU.BL.IC.IP
ns1              IN      A       PU.BL.IC.IP


you have to put internal Ip

if your Dns server would connected via public directly then you had to use public ip but your one is behind router and configured with internal ip

If I put the local network address wouldn't it return that to the client, ie connecting from the outside world for example.com the dns would return 192.168.1.4 how would the client connect to that?

Explain if I missed something

Well it just started working, and I did have the public IP in the zone.

good!!
ok so what Ip you put in named.conf ??

in allow section ??
