Networking, DNS behind router with bind9

I'm just having the hardest time with something I consider should be easy.  I have the following

Static IP
Router w/portforwarding to my server and port 53 tcp/udp for dns to the same machine
Server is behind the router

I want to setup dns on the server so that I can have my domain.com go to the server.

I've set up a zone for domain.com and reverse dns.   I think Im close but just missing something,

Thanks!

I've set up reverse dns

Doesnt seem to be working.

And I've set up reverese dns for the public facing IP (my server is on 192.168.1.4, locally)

But that doesnt seem to be working, I just thought

My zone file for my domain 
 
$TTL 3D
 
 
@ IN    SOA     ns1.example.com. admin.example.com. (
   2007062001
   28800
   3600
   604800
   38400
);
 
 
example.com.      IN      NS              ns1.example.com.
example.com.      IN      MX     10       mta.example.com.
 
 
www              IN      A       PU.BL.IC.IP
mta              IN      A       PU.BL.IC.IP
ns1              IN      A       PU.BL.IC.IP
example.com.     IN      NS      ns2.example.com.
 
My reverese dns zone file
 
$TTL 3D
 
@       IN      SOA     ns1.example.com. admin.example.com. (
                        2007031002
                        28800
                        604800
                        604800
                        86400 )
                    IN    NS     ns1.example.com.
IP                   IN    PTR    example.com
 
#where IP is the last digit of my public ip
 
 
my named.conf file has the following
 
zone "example.com" {
        type master;
        file "/etc/bind/zones/db.example.com";
        };
 
# PU.BL.IC.IP = public ip address
zone "IC.BL.PU.in-addr.arpa" {
     type master;
     file "/etc/bind/zones/rev.IC.BL.PU.in-addr.arpa";
};
