My iptables replied:
iptables: No chain/target/match by that name.
How is it created?
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.
