If an interface is not assigned any zone, it is automatically assigned <code>external</code> 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>Opening Custom Ports</title><para>Cockpit app provides advanced management of firewall. Both FreedomBox and Cockpit operate over firewalld and are hence compatible with each other. In particular, Cockpit can be used to open custom services or ports on FreedomBox. This is useful if you are manually running your own services in addition to the services provided by FreedomBox on the same machine. </para><para><inlinemediaobject><imageobject><imagedata fileref="https://wiki.debian.org/FreedomBox/Manual/Firewall?action=AttachFile&amp;do=get&amp;target=firewalld-cockpit.png"/></imageobject><textobject><phrase>firewalld-cockpit.png</phrase></textobject></inlinemediaobject> </para></section><section><title>FreedomBox Ports/Services</title><para>The following table attempts to document the ports, services and their default statuses in FreedomBox.
