    I use ISPConfig for several years and the first time I can not solve the problem yourself. There also found nothing that worked on the internet or in the forum.

    ISPConfig ##### #####
    ISPConfig version is 3.0.5.4p8

    CHECK VERSION ##### #####
    [INFO] php (CLI) version is 5.6.14-0 + deb8u1
    [INFO] php-cgi (used for cgi php in default vhost!) Is version 5.6.14-0 + deb8u1

    Sytem Debian Jessie updated, installation as described in https://www.howtoforge.com/tutorial/perfect-server-debian-8-jessie-apache-bind-dovecot-ispconfig-3/

    When Ispconfig Firewalls in the System -> Firewall menu is on, server stops resolve domain names to IP address.

    According to one of the guides I added parameter of listen-on port 53 {any; }; /etc/bind/named.conf.option file - it has not changed anything.

    When the Ispconfig firewall is turned ON:

    Is this a virtual server? There can be problems on servers that use openvz / virtuozzo when using iptables firewalls.

    Exactly! This is my first VPS server. Until now, I put servers as independent units.

    So take advantage of the firewall, which is in panel of VPS Provider and ISPConfig firewall leave off?

    Yes, if the provider has a firewall, then use that one.
