  <title>Gaitu edo blokeatu suebakiaren atzipena</title>

  <p>GNOME does not come with a firewall, so for support beyond this document
  check with your distribution’s support team or your organization’s IT department.
  Your computer should be equipped with a <em>firewall</em> that allows it to
  block programs from being accessed by other people on the internet or your
  network. This helps to keep your computer secure.</p>

  <p>Aplikazio anitzek erabili dezakete zure sareko konexioa. Adibidez, fitxategiak partekatu ditzakezu edo beste norbaitek zure mahaigaina urruneko sare batetik ikusi dezan ahalbidetu dezakezu. Zure ordenagailua nola konfiguratuta dagoen, agian suebakia doitu beharko duzu zerbitzu horiek espero den moduan funtzionatu dezaten.</p>

  <p>Each program that provides network services uses a specific <em>network
  port</em>. To enable other computers on the network to access a service, you
  may need to “open” its assigned port on the firewall:</p>


  <steps>
    <item>
      <p>Go to <gui>Activities</gui> in the top left corner of the screen and
      start your firewall application. You may need to install a firewall
      manager yourself if you can’t find one (for example, GUFW).</p>
    </item>
    <item>
      <p>Open or disable the port for your network service, depending on
      whether you want people to be able to access it or not. Which port you
      need to change will <link xref="net-firewall-ports">depend on the
      service</link>.</p>
    </item>
    <item>
      <p>Save or apply the changes, following any additional instructions given
      by the firewall tool.</p>
    </item>
  </steps>
