To further clarify, if you are using the GNOME variant of Fedora, the commands 
you'll need to run are:

Step 1: `sudo firewall-cmd --set-default-zone=public`

After this, you'll want to get the name of the primary interface. You can do 
this with a few commands, I recommend `ip link`. It will likely begin with 
'enp', for example, 'enp0s1'.

Then you would run the following command with that interface name:
`sudo firewall-cmd --change-interface=enpXsY --zone=public`

For example, `sudo firewall-cmd --change-interface=enp0s1 --zone=public'

This exact scenario is why I don't believe the GNOME Spin should have ever 
been allowed to effectively disable the firewall with their absurd 
FedoraWorkstation firewall zone.
