DNS problems

[coffeeninja]

Hi, came here to get some fresh eyes on my DNS problem.
I have tried to setup a dns server with bind9. Things went okay until i started trying to dig/nslook/ping the dns, which did not respond. Both my zone file and reverse lookup zone file are okay according to named-checkzone.

Here is the config:

domain=isp2.datornatverk.se
domain ip=192.168.20.20
dns ip= 192.168.20.20
nameserver ip =


<//etc/resolv.conf//>
// replace example.com with your domain name, and 192.168.0.1 with the address of your new DNS server.
search isp2.datornatverk.se
nameserver 192.168.20.20
nameserver 130.240.136.144

<//etc/bind/named.conf.options//>
options {
   directory "/var/cache/bind";

   forwarders {
   130.240.136.144;
   };

   auth-nxdomain no;    # conform to RFC1035
   listen-on-v6 { any; };
};

<//etc/bind/named.conf.local//>

//
// Do any local configuration here
//

// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";

zone "isp2.datornatverk.se" {
        type master;
        file "etc/bind/zones/db.isp2.datornatverk.se";
        };

zone "20.168.192.in-addr.arpa" {
     type master;
     file "etc/bind/zones/rev.20.168.192.in-addr.arpa";
     };

<//etc/hosts//>

Any help would be appreciated.
