Hi Doug,
Since firewalld didn't recognize that chain I'm starting to wonder if
you are even running a firewall on your system which, if not, puts
your system at great risk.
As root type "iptables-save". If you get a lot of output you have
some sort of firewalling in place. If there is nothing there or only
the two rules I provided earlier you do not have a safe machine
because there are no firewall rules in place. If that is indeed the
case you need to search for how to turn on a firewall on fedora and
make that your priority.

I have no
firewall. What I want is something like Windows has:
Bitdefender, or Malware Bytes. If I turn on any of the suggested
firewalls, something that I
use will probably be blocked--email, Google, something. Sorry I'm just
too stupid to understand this. I don't normally ever boot into Windows,
but I have it on a couple
of machines--not this one.
