trying to set up own my dns

I'm trying to set up my own webserver/dns/mail etc, but I'm having a little trouble.

I have a local lan with 3 linux and 1 windows machine. The connection is hooked up to a linux box with two interfaces. eth0 ip addresses 192.168.0.1 for local and ppp0 68.209.106.247 for public . the local network is nasdrak.com. So, for instance, a machine named nina is can be refered to nina.nasdrak.com (only withi the lan). I own the domain nasdrak.com, but the dns is been managed by another company(for now, muh ha ha ha). I set up the apache webserver fine. I want to set up the webserver as a dns as well, but I'm having a little trouble.

I own the name floatingtarget.com. I want to set a dns server to manage that name, but aparently I'm doing something wrong. Let me give you the details and maybe one of you guys can help me.

the router/webserver/future-dns-server:
local-ip: 192.168.0.1
public-ip: 68.209.106.247
os: Redhat 9
apache: 1.3.28
bind9
hostname: nina or nina.nasdrak.com

Like I said before, I want to set up a dns server to manage the domain floatingtarget.com.
The are the files I have

// /etc/named.conf
// bind config file

options {
directory "/var/named";
};

zone "floatingtarget.com" in {
type master;
file "floatingtarget.com.db";
};

zone "." in {
type hint;
file "named.ca";
};

// /var/named/floatingtarget.com.db
$TTL 86400
floatingtarget.com. IN SOA nina.nasdrak.com. kubicon.myself.com. (
1 ; serial
10800 ; refresh
3600 ; retry
604800 ; expire
86400) ; minimum ttl

; nameservers

floatingtarget.com. IN NS nina.nasdrak.com.

;
; public servers
nina.nasdrak.com. IN A 127.0.0.1
nina.nasdrak.com. IN A 68.209.106.247

I'm certain I'm doing something wrong cause when I go to the control panel of my name registrar and change the dns record to point to my machine (68.209.106.247) it says


I use named-checkconf and named-checkzone to verify the syntax of the files and they don't return errors.

thanks for the help in advance.
