Hello! I recently tried an Ubuntu 12.10. It was checked against falko's perfect server tutorial, install process was pretty much the same. Enviroment: Server is located behind a router, internal ip 192.168.111.251. Router has all the relevant ports (ftp, ssh, mail, dns, web, https) forwarded to this ip. Problem: I created the nameservers in ispconfig via the dns config wizard and checked their creation manually in /etc/bind. Then from my registrar, I pointed the example.com domain to the newly created nameservers. After waiting for some time for DNS to propagate, I realised something was off - basically I think I'm facing a circular reference problem. My dns records look like this: /etc/bind/pri.example.com [BM--] 0 L:[ 1+ 0 1/ 17] *(0 / 698b) 0036 0x024 $TTL 3600 @ IN SOA ns1.example.com. daseagle.gmail.com. ( 2013011101 ; serial, todays date + todays serial # 7200 ; refresh, seconds 540 ; retry, seconds 604800 ; expire, seconds 86400 ) ; minimum, seconds ; example.com. 3600 A 18.104.22.168 example.com. 3600 MX 10 mail.example.com. example.com. 3600 NS ns1.example.com. www 3600 A 82.208.XXX.XX mail 3600 A 82.208.XXX.XX --- Help? I really don't know how to get around it.
