GUFW or GUI for uncomplicated firewall
One of the basic and important defenses that one should have when going online is a firewall, this is needed to prevent those overly nosey people who would try to attack you computer.Or the firewall can be used to control the Data that you recieve.
Ubuntu comes with a Firewall aswell, (UFW) it is a very simple firewall and works very effectively.This firewall is basicly controlled via the terminal.Since most of the beginers are a bit cautious in using the terminal. Thanks to Marcos Alvarex Costales, Gufw was created by him.
Gufw alows you to control the firewall via this program..
The usage of this program is pretty basic and requires no explanation.. after u have installed the program, runnin it will provide you with an interface,here you need to add rules for the firewall. 3 tabs are present Simple, Preconfigured and Advanced.
Simple rule
The Simple allows you the allow or deny, data coming through a certain port. You can decide on wich method to block them or allow them, tcp, udp or both. Press the add button and the rule is added.
Preconfigured rule
Here you get to allow or deny an entire service or program.
Deniable/allowable services include : http, https, ftp, nntp, etc..
Advanced rule
Here you get to allow or deny by range of IP addresses and ports.
Simple enter the range from and to include the ports and then press add.
Hope this helps you out. with the use of this firewall.
Thank you for that. I didn’t know about UFW.
