Hi all, I want to create my own domain server. I registered few domains using with godaddy. And my main domain is voipdeniz.com. I create my own nameserver ns1.voipdeniz.com ns2.voipdeniz.com Using Host Summary on godaddy panel, I also have EC2 server on amazon web services with elastic IP 126.96.36.199 and domainname is ns1.voipdeniz.com I installed fully ISPConfig 3 and I think it works well. But when I try to set any domain's name server to my server, It cannot resolve name. For example, I have another domain wich name is my brother company name like marjinalmiddleeast.com. I set the name server as ns1.voipdeniz.com and ns2.voipdeniz.com on registrar panel. I also add this domain my ISPConfig 3 panel on DNS tab. But, When I try to nslookup to this domain, it cannot resolve name. What should be wrong?. Please help me. Thanks for answers.
