DNS Issues (Noob)

[MacBros]

I installed ISPConfig, and got a domain through GoDaddy, and setup nameservers (ns1 and ns2) on that domain to my external IP. I also added A Records in ISPConfig for ns1 and ns2 to my external IP. I can't connect through my domain, but can through my external ip and I've waited 24 hours incase DNS had to update. Here's what I get with dig @localhost mydomain.com:



[root@server1 install]# dig @localhost macbrosgb.com
; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_5.3 <<>> @localhost macbrosgb.com
; (1 server found)
;; global options: printcmd
;; Got answer:

[root@server1 install]#


Any help is really appreciated.

Oh, and I'm using Bind9 on a CentOS 5.5 system.
