NAME

       Gufw - Graphic user interface for managing ufw

DESCRIPTION

       Gufw is an easy to use Ubuntu / Linux firewall, powered by ufw.

       Gufw  is an easy, intuitive, way to manage your Ubuntu firewall. It supports common tasks such as allowing or blocking pre-configured, com-
       mon p2p, or individual ports port(s), and many others! Gufw is powered by ufw.  Introduction iptables is already a very	powerful  tool	by
       itself,	but  it's  syntax  can	get awkward at times and hard to figure out, so Ubuntu developers decided to make ufw ("The reason ufw was
       developed is that we wanted to create a server-level firewalling utility that was a little bit more for `human beings`"), which was  to	be
       simpler.  Now,  on  the graphical side of things, Firestarer already existed. But why not make an even easier to use GUI for desktop `human
       beings`, powered by ufw? This is where Gufw comes in.

RUN

       You can run Gufw in GNOME menu: /System/Administration/Firewall configuration

USAGE

BASIC SETTINGS

       Gufw has two states: Enabled and disabled.  When Gufw is enabled, you can allow/reject/deny all incoming and outgoing connections.

ADD SIMPLE RULE(S)
       You can specify the port or service, and protocol to be allowed (allow traffic), reject (reject traffic without reply), denied (deny  traf-
       fic with reply), limit (limit traffic) on the host, or limit an IP or Port (Protecting against brute-force login attacks).  The port can be
       a number of 5 digits, from 1 to 65535.  The service can be any of /etc/services file (By example tcpmux, echo,  discard,  systat...).   The
       protocol can be:
	  1. TCP: Apply rule for all traffic in protocol TCP.
	  2. UDP: Apply rule for all traffic in protocol UDP.

	  3.  From  Port:  You	can allow/deny/reject/limit traffic from a port. This parameter is optional. The port can be a number of 5 digits,
       from 1 to 65535. You can use a range ports with this format port1:port2 (by example 3234:3237), or add multiple ports with port1,port2  (by
       example 3234,3254).
	  4. To IP Addres: You can allow/deny/limit traffic to an IP address. This parameter is optional. Example for a range: 192.168.1.0/9
	  5.  To Port: You can allow/deny/reject/limit traffic to a Port. This parameter is optional. The port can be a number of 5 digits, from 1
