Good evening everyone,
my network is configured like this:
- In my network I have a dns server
- ipfire is configured to give, using dhcp, as the dns address of my server
My question is:
How do I make ipfire reject all DNS requests that we don’t have as addresses from my DNS Server?
Basically I want to avoid setting a DND Server different from my server by hand, of course I could do it with windows rules, put users in a group that does not have the possibility to make these changes, but I would like to understand how to do it with ipfire.
