        firewall-cmd --reload should do the trick, I think?

        He says he got that step.

        I'm wondering about a typo in the port command.

        firewall-cmd can show the rules too.

          Hmmmm.....

          Doesn't seem to be adding....

          sudo firewall-cmd --list-all
          
          public (active)
            target: default
            icmp-block-inversion: no
            interfaces: enp6s0f0
            sources:
            services: dhcpv6-client ssh
            ports:
            protocols:
            masquerade: no
            forward-ports:
            sourceports:
            icmp-blocks:
            rich rules:

            I can't remember the syntax to show the rules. --show-all maybe.

                    turn off selinux, confirm it all works, turn it back on and add an exception.

                        Important to note: Those are not permanent and will not survive a --reload .

                        Edit: You beat me to it.
