Strange DNS error

Post by bertalanimre » 2017/11/06 09:49:34

Hey Forum,

I've installed a CentOS 7.1 minimal as a Firewall for my network. All worked fine until the server got reboted. Then the domain names are not resolved for the clients and the server itself until I simply systemctl restart network. Now the server can resolve the domain names, but the clients are still unalbe to do so.

What went wrong? The server and all the clients are static, no DHCP present in the network, therefore no BIND nor dnsmasq. The network is masquared by firewalld.

The issue was with firewalld. The previous sysadmin didn't make the settings permanent. So I've just enabled DNS service for the internal zone and all good to go.
