  <section>
    <title>Firewall</title>
    <para>Firewall is a network security system that controls the incoming and outgoing network traffic. Keeping a firewall enabled and properly configured reduces risk of security threat from the Internet. </para>
    <para>The operation of the firewall in Plinth web interface of FreedomBox is automatic. When you enable a service it is automatically permitted in the firewall and when you disable a service it is automatically disabled in the firewall. For services which are enabled by default on FreedomBox, firewall ports are also enabled by default during the first run process. </para>

    <para>Firewall management in FreedomBox is done using <ulink url="https://fedoraproject.org/wiki/FirewallD">FirewallD</ulink>. </para>
    <section>
      <title>Interfaces</title>
      <para>Each interface is needs to be assigned to one (and only one) zone. Whatever rules are in effect for a zone, those rules start to apply for that interface. For example, if HTTP traffic is allowed in a particular zone, then web requests will be accepted on all the addresses configured for all the interfaces assigned to that zone. </para>
      <para>There are primarily two firewall zones used. The <code>internal</code> zone is meant for services that are provided to all machines on the local network.  This may include services such as streaming media and simple file sharing.  The <code>external</code> zone is meant for services that are provided publicly on the Internet.  This may include services such as blog, website, email web client etc. </para>
      <para>For details on how network interfaces are configured by default, see the <ulink url="https://wiki.debian.org/FreedomBox/Manual/Firewall/FreedomBox/Manual/Networks#">Networks</ulink> section. </para>
    </section>
    <section>
      <title>Ports/Services</title>
      <para>The following table attempts to document the ports, services and their default statuses in FreedomBox. If you find this page outdated, see the Plinth source for <ulink url="http://sources.debian.net/src/plinth/latest/data/usr/lib/freedombox/first-run.d/90_firewall">lib/freedombox/first-run.d/90_firewall</ulink> and Firewall status page in Plinth UI. </para>
