I am trying to add a rule to “Force clients to use IPFire DNS Server” by following the instructions within the wiki.
Following the steps near the end under the category “Protocol” I have selected “Service Groups” however, nothing shows up in the drop down menu, as such, I can’t select “DNS (both)”.
Thank you very much for the help. I haven’t tried it yet (busy with family), but it is very clear, so I am confident that it will work. I just didn’t realize that the groups were not already created and selectable. I failed to properly read the top of the wiki page that tells me how to create a service group.
My biggest issue is a search for a reliable content filtering option, still working on that.
