How is WHAT created? I'm snowed!
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.
