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,
       common  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.

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 PRECONFIGURED RULE(S)

       You can select between more Programs and Services preconfigured.   Once
       Program/Service can have multiples rules.

REMOVE ONE RULE

       Steps:
          1. Select a rule in the list.
          2.  Click in Remove button.  You can delete more rules if you select
       it.

RESET CONFIGURATION

       You will remove all rules and reset the ufw  configuration  to  initial
       status (disable)!

EDIT PREFERENCES

       You can edit your preferences in /Edit/Preferences menu.

IP/PORTS FORWARD

       To routing policy and rules, you must setup IP forwarding:
          Close Gufw
          Uncomment the following lines in /etc/ufw/sysctl.conf:
             net/ipv4/ip_forward=1
             net/ipv6/conf/default/forwarding=1
             net/ipv6/conf/all/forwarding=1
          Restart firewall:
             ufw reload
          Open  Gufw  again:  You'll  see a new "Routed" option (with an arrow
       around the shield) and you can forward any rule from the Update  window
       or Advanced Tab in Add window.

USE GUFW WITHOUT GRAPHICAL ENVIRONMENT OR REMOTE COMPUTER

       You  can use Gufw in a Linux without Graphical Environment (for example
       an Ubuntu Server) or from a remote computer. You will need Gufw 13.10.2
       or  higher. Just export your X Display. All the operations in Gufw will
       be apply in the remote computer.  Important: If you enable the firewall
       under  ssh  without the ssh rule, you'll close the ssh connection, then
       before to enable Gufw under a ssh connection, append the ssh rule using
       ufw with this command:
           sudo ufw enable ssh Linux, for example:
           Remote  computer  without  graphic environment (IP = 192.168.1.102,
       Gufw installed and ssh server).
           Local Linux. In this local computer, open a Terminal and  run  this
       command:
             ssh user_remote@192.168.1.102 -X
             sudo /usr/bin/gufw-pkexec -ssh Windows (For example, Windows IP =
       192.168.1.101; Linux IP = 192.168.1.100):
           Install Putty & Xming.
           In Windows: Run XLaunch from the Start Menu and  check  "No  Access
       Control" in the last step.
           Connect to your Linux with Putty and run:
             export DISPLAY=192.168.1.101:0.0
             sudo /usr/bin/gufw-pkexec -ssh
