As summarized in the topic, name resolution via IPFire has not worked since the upgrade.
Before the upgrade, I had entered the primary and secondary DNS server of my cable network operator in the IPFire and configured the IPFire as the DNS server for the clients in the DHCP settings.
After the upgrade, the WebUI shows the status Broken under Network> Domain Name System (see screenshot below).
At times I did not specify the IPFire as the DNS server in DHCP, which in my opinion. undermines the sense of the firewall and makes access to the servers under the orange network more difficult.
I have two questions:
- What is the cause of the status or how can I determine the cause?
- Why can’t I delete the two servers under Action? (I could easily delete a third name server again.)
Thank you for your support.
