by the way if you have just one public IP , there are some free services out there and they will host for you a slave dns server for the outside world ...one of them is buddydns if i'm not mistaken
How would I do the slave to buddydns since in ISPConfig I have set ns2 as a mirror to ns1? Would I just use the zone transfers section? And just to make sure I have this right, only forward DNS traffic to the primary dns server correct, and the mirror don't forward traffic to it
