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
