DNS Confused

Confused DNS

I want my own DNS, but no himself really I eat to configure them and if this is possible .

I have my server with a router and the local address is 192.168.2.3

I have an own I.P.: xx.xx.xx.xx

My server hostname is : server1.example.com

I want in my provider of domains that all I have registered point to my own I.P. : ns1.example.com - ns2.example.com

This my current config, and not work :

DNS ZONE

Server : server1.example.com
Client : mynameclient
Zone (SOA) : server1.example.com
NS : ns1.example.com
email : [email protected]
Refresh, Retry, Expire, Minimum and TTL (default with ISPConfig 3)
Allow zone transfers to these IPs (comma separated list) (blank)
Active : checked

RECORDS:

A mail xx.xx.xx.xx 0
A ns1 xx.xx.xx.xx 0
A server1.example.com xx.xx.xx.xx 0
A www xx.xx.xx.xx 0
MX server1.example.com mail.example.com 10
NS server1.example.com ns1.example.com 0
NS server1.example.com ns2.example.com 0

I Prove:

server1:/# nslookup example.com
;; Got SERVFAIL reply from 89.29.252.2, trying next server
;; Got SERVFAIL reply from 89.29.252.2, trying next server
Server: 89.29.253.2
Address: 89.29.253.2#53

** server can't find example.com: SERVFAIL

Would they be so kind from explaining me with these data of example like to configure correctly the Zones DNS?

Thanks in advance.

1 My own I.P. :xx.xx.xx.xx
2 The I.P. of the Router 192.168.2.3
3 Or who ?

And in DNS, ZONE (SOA) that I have put:

1 My Hostname and domain : server1.example.com.
2 My Domaian only : example.com.
