So what I could come up with is this:
You have a host on your network that does not use your DNS servers.
You have a host on your network that does not allow you to put in custom DNS servers.
I would simply say: Throw them away. That is not network equipment. It simply is a bug, and that should not be fixed by us.
Agreed.
But I guess the situation some people have in mind is that you have *users* in your network you can't really control or trust not to mess up with DNS settings in their machines. As in, children.
Or you have *machines* (in this case, Apps) you can't control, because they don't even have an input field for "DNS".
But any kid smart enough to change DNS settings in their laptop or whatever is also smart enough to work around such redirection.
I'm curious. How could this be done? I have tested the REDIRECT rules with various arbitrary entries, even with non-existing addresses. So far, DNS queries were always redirected to the DNS servers specified in IPFire until now. I even didn't notice that I tested withirregular or invalid addresses.
