Congrats, you've created a firewall ruleset just like the default, but
without ssh. You could have:
`firewall-cmd --remove-service ssh --permanent `

You can read about firewalld at https://fedoraproject.org/wiki/FirewallD .
If you prefer to disable firewalld and use iptables, there are instructions
on the same page.
