I have one static ip (ie. 188.8.131.52). I connect the ADSL modem to a router. I setup my Ubuntu server and ISPConfig with internal IP (192.168.0.100) I would like to register my own primary & secondary DNS in NameCheap or GoDaddy. (ie. ns1.myserver.com, ns2.myserver.com) Because I don't want to use the registrant's DNS servers. When I setting up the server, I use 192.168.0.100 as the server IP and hostname is ns1.myserver.com, how can I setup the ns1 and ns2 after I have installed the ISPConfig? Anyone can help me? What is the procedure for me to setup the primary & secondary DNS correctly? So that the outside world can read my zone records correctly. (I forward all the ports from my router to the internal IP address - 192.168.0.100) Thanks!
