First, there is no GUI by default installed for Ubuntu desktop firewall. Second, and more important, Linux OS, thus Ubuntu too, is much more secure than Windows. Reason is that Ubuntu don`t open ports by default. Manage firewall on Ubuntu without GUI is not so easy when you are beginner.
You can simply enable disable firewall by typing following syntax in terminal:
- For enabling
$#sudo ufw enable
- For disabling
$#sudo ufw disable
Please remember that Ubuntu firewall is disabled by default.
I`ll stop here with CLI configuration of firewall. Since we are talking about Ubuntu desktop I`ll switch to firewall GUI.
First you have to install GUI for firewall. Go to Terminal and type following syntax followed with administrator password
$#sudo apt-get install gufw
When it`s installed go to System Settings and you will see new icon as is on slide 1.
Select the Firewall Configuration and you will see that firewall is disabled (Slide 2).
Select Status sliding button to ON in order to enable firewall. Notify change on slide 3. Now your firewall is enabled.
In next tutorial I`ll show you basic Ubuntu Firewall configuration.
