I'm totally new to Linux, so please take it easy on me I have a linux box (FC6) behind the router, with the local IP address 192.168.0.10 that is NAT-ed through the router to the Internet and is presented as 18.104.22.168 (example). I also have a domain domain.net registered on the Internet Register. Now let's go to the questions 1. In the ISPConfig setup, one of the very last questions was IP address, and I've typed in my global IP address (22.214.171.124), is this correct? The host is called test and the domain is domain.net, so ISPConfig is accessible via https://test.domain.net:81 I've created new client AABBCC with their internet domain www.aabbcc.com (example) 2. Now, if I look under DNS under the client AABBCC, I can see that Nameserver 1 and Nameserver 2 are test.domain.net is this correct? 3. On the Records tab I HAVE The following: For the A records Code: IP-Adresse Hostname 126.96.36.199 www and for the MX records Code: Mailserver Hostname test.domain.net www is this correct? 4. The domain www.aabbcc.com is registered on the Internet Register. What should I use as my namserver address. ns1.domain.net and ns2.domain.net (have made these in advance) or test.domain.net (that is the address of the box with ISPConfig)?
