apache and bind9

I want to host 5 website on cubieboard 1.  So i decided to use bind9 as dns server to add in bigrock and godaddy. I am using this tutorial http://www.servermom.org/how-to-install-and-setup-bind9-on-ubuntu-server/   for setup and its works.This issue is some applications are working and some are not.please understand lan and wan in this. Wan is external ip address (122.152.157.5) and lan is internal ip address (192.168.1.2).All applications are configured and test with lan,wan and domain name. dns already added to godaddy and bigrock

Apache: not working with domain.On wan is going to 192.168.1.1 and on lan, its working

webmin: working with all lan,wan and domain

proftpd: not working with domain and wan but working with lan ip

qbittorrent: working with all lan,wan and domain

So i am searching more and find out etc/resolv file have namesaver 192.168.1.1. When i am try to change with lan ip. After reboot it comes back to 192.168.1.1.Now i dont know what to do?

My issue is i want to host my 5 website on cubieboard and add dns to domain registrar. Please find attachment of conf file. There are bind9 , hosts and hostname files
