Remove dns entries only works from old servermanager

NethServer can’t work without the nethserver-firewall-base package installed, it’s mandatory.
This status reinforces my idea that the system is in bad shape. While it is possible to fix the system (experts* only) the safest option is to reinstall from scratch.

  • Experts on CentOS/RHEL is enough, experts on NethServer a plus, but it may be harder to hire one of them. :slight_smile:
