WHM - Setting up private BIND DNS server

Question

I can't find any complete guide on how to get this working on a VPS, my current problems is:

In Basic cPanel & WHM Setup when I set ns1.domain.com and ns2.domain.com as Nameserver 1 and 2, when I press the Assign IP Address button, it assigns an ip address that I can't ping/telnet neither through internet nor in the lan of my box. Is this correct, should this ip be accessible online ?

Answer 1

cPanel&WHM is not intended to be used within a NAT setup (where private IPs are present and/or bound to the server). cPanel&WHM is not NAT-aware so it assumes every IP bound to the server is publicly accessible. Hence the system requirement of being on static publicly visible IP address(es):
