Some applications use different ports, instead of an only port. It’s possible to specify port ranges with UFW. There are other ways to allow connections, other than specifying a port or service. HTTPS on port 443, which is what encrypted web servers use, through ufw allow https or ufw allow 443 HTTP on port 80, which is what unencrypted web servers use, through ufw allow http or ufw allow 80 Happily, you already know how to write rules that allow connections based in a name or service port we already made it through SSH on port 22.

UFW (uncomplicated firewall) is a firewall configuration tool that runs on top of iptables, included by default within Ubuntu distributions. Run the ufw status verbose command to see the defined rules. Answer the prompt with y and press ENTER. We already set up a firewall rule that allows SSH connections, so it might be good to continue. You’ll get a notice telling that the command can interrupt the existing SSH connections. It provides a command line interface and aims \ to be uncomplicated and easy to use."
