I'm trying to setup my first BIND9 DNS server for a small local network and can't seem to get it working. I want to create a 'local' domain of max.app
As far as I can tell named is running, but it doesn't seem to be serving my domain records?
service named start
Returns OK, and the demon is running on boot.
If I try and ping mac1 I get: unknown host mac1
If I try and ping mac1.max.app I get: unknown host mac1
When I try nslookup I get:
nslookup max.app
Server: 8.8.8.8
Address: 8.8.8.8#53
Non-authoritative answer:
Name: max.app
Address: 67.192.47.244
As you can see I'm not serving records from my local bind service (192.168.100.10)
My /etc/resolv.conf file looks like this:
# Generated by NetworkManager
search max.app
nameserver 192.168.100.10
nameserver 8.8.8.8
nameserver 8.8.4.4
My /etc/named.conf file looks like this:
acl local-network { 192.168.100.0/24; };
options {
listen-on port 53 { 127.0.0.1; 192.168.100.10; };
listen-on-v6 port 53 { ::1; };

allow-update { none; };
};
zone "100.168.192.in-addr.arpa" IN {

file "max.app.rr.zone";
allow-update { none; };
};
My /var/named/max.app.zone file looks like this:

Service named status returns:

named (pid 1121) is running.
This "number of zones: 15" seems a bit odd? When I only have 1 zone defined in named.conf
UPDATE 7/14 5:45PM CST
Ok I've followed the suggestions below but things still don't seem to want to work.
Added to /etc/sysconfig/iptables
