Hi All, I installed isconfig(ISPConfig Version: 3.2dev20201119) a few days ago following link (https://www.howtoforge.com/tutorial...l-pureftpd-bind-postfix-doveot-and-ispconfig/) and it s completed without any error. I oppened a dns zone for test but i can t reach on my test account. Dns working, firewall rules ok and if i send dig +short @93.x.x.13 NS k***m.com returning result but when i m trying to ping it s not answering. ns3.s***k.name.tr. ns4.s***k.name.tr. Also i ve Microsft Dns server if i create zone on it, it s working perfect. Do you have any idea or offer whats happening on it. By the way i bought support from schaal it but we can t solve. Thanks for your help.
