       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
