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 Linux 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 , runs on Ubuntu, and anywhere else Python, GTK, and Ufw
       are  available.   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 PRECONFIGURED RULE(S)

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

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 traffic
       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. both: Apply rule for all traffic in protocol tcp and udp.

ADD ADVANCED RULE(S)

       You can add an advanced rule.  You can specify:
          1. Protocol: tcp, udp or both.
          2. From IP Addres: You can allow/deny/reject/limit traffic  from  IP
       address. This parameter is optional or you can use "Any". Example for a
       range: 192.168.1.0/9
          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 or you can use "Any". 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 to
       65535. You can use a range  ports  with  this  format  port1:port2  (by
       example 3234:3237).

GENERAL TO PRECONFIGURED / SIMPLE / ADVANCED

       With  the  extended parameters you can: Insert a rule in a specific row
       Set the log level for ufw.

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 intial
       status!

EDIT PREFERENCES

       You can edit your preferences in /Edit/Preferences menu.  Preferences:
          1. Register Gufw log: You will have got a log of all  operations  of
       Gufw.
          2. ufw log enabled: You will enable/disable and set the level of the
       ufw log.

LISTENING REPORT

       You can enable the Listening Report in  the  Preferences  window.   The
       listening  report  will  display  the  ports  on the live system in the
       listening state for TCP and the open  state  for  UDP.  It's  the  same
       report that the listening report in ufw.

NOTES

HOW TO AUTOSTART GUFW WITH THE SYSTEM?

       A  short  answer  is,  you really don't need to autostart Gufw. Gufw is
       just a settings tool for ufw (the real firewall), and  they  are  split
       separate.   Think of Gufw as a settings dialog. After you do all of the
       changes and close it, the settings are still in  effect  (for  example,
       when  you  setup a new printer - after you close the setup window, your
       printer setup still stays!).  So there is no need to add Gufw to  auto-
       start,  unless  you're  going  to  change  your  firewall settings very
       frequently. If you enable the firewall and  close  Gufw,  the  firewall
       will  still be enabled, even after a reboot.  REMEMBER: Once configured
       it will stay that way, so you don't need to be  running  Gufw  on  your
       desktop all the time!
