Simple: If you haven't got any network services running besides cups and ssh, then no ports besides 631 (cups) and 22 (sshd) are open because no services are listening behind them. A port just means a daemon/service listening for incoming traffic. So no open ports means no services listening and that should suit you. A "firewall" is needed if you want to filter access to offered networking services. It is unneccessary if you do not want to offer services to the internet because you can shut them down or just let them listen to localhost (at least, you can do that with cups and ssh). To do that for cups, you just put these lines in /etc/cups/cupsd.conf: listen localhost:631 Browsing = off (or Browsing off , I just can't remember which right now) Now, cups will only listen on localhost (127.0.0.1).
