At least in KDE, possibly not in GNOME as it lacks many of the features available in KDE, you can specify the zone of the connection in your NetworkManager configuration GUI.

We used to have this for a long time, but removed it recently because the firewall zones were never really used for anything. We just have a Workstation zone that we expect users to not change. (But of course, if you want to change your firewall settings, you can change it if you want to.)
