I have completely configured DNS BIND9 server on ubuntu server 12.xx but i think it is working as open DNS how i will avoid this Senario I have 4 computers having IPs
winpc1=192.168.1.50 winpc2=192.168.1.51 winpc3=192.168.1.52
I have one LINUX Server having IP 192.168.1.30 static obviously
My Router Address is 192.168.1.1
Now these Boxes are connected via Router's Ports every one can ping each other DNS BIND9 doing caching as well all goes well but...... How i will stick my DNS to only this network so that no other PC can access it
I mean what Should i add to named.conf.local ????
