The firewall should be active all the time after you enable it ONE time. To check if the firewall is enabled:
Code:
 sudo ufw status verbose

The linux firewall is iptables. What you have is an interface that allows easier customization of iptables. Iptables is a very powerful firewall with tons of options. Take the time to learn the gui, but also learn what is under it. There are times where getting under the hood is the only way to get what you want.
