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.
