Recently I've installed 'The Perfect Server – CentOS 7 (Apache2, Dovecot, ISPConfig 3)'. Everything seems to work, except I can't access server via domain (only with external ip address). I have created nameservers in my registrar and whois is working. Is it posible to post any configuration code here to find out if the fault is there? Is it posible the problem is in my ISP? Thanks in advance (I have to mention that I am noob at this) I'm pretty sure that the problem is in Bind's configuration. What files should I post here?
