Once you've switched Firewalls, go to your Network Manager settings, select the WiFi/Ethernet connection you wish to customize, click the "General" tab, and then go to "Firewall zone" and chose between something like "home" or "public".

Also, an extra GUI app called "Firewall" or "firewall-config" should've been installed too. If not, go to you package manager and search for it, it usually has a brick wall icon. Let's you customize each zone.

Note, just realized Gnome has no Firewall integration in its settings panel at all, unlike KDE.

So for Gnome users, just install firewall-config GUI and you can customize which zones each network connection uses from there.

On KDE, you can customize zones as I described above, or use the GUI app.
