Step 5 - Check Firewall Settings
--------------------------------

SavaPage uses TCP/IP port ``8631`` (for HTTP), port ``8632`` and ``8633`` (for
HTTPS/SSL) and port ``9100`` (for JetDirect/RAW printing) by default.

.. note::

   You can change the TCP/IP interface and port defaults in the
   :ref:`server.properties <ch-install-on-linux-config-server-properties>`
   file after installation. 
   See :ref:`Alternative TCP/IP Interface and Ports <ch-install-on-linux-advanced-config-alt-tcpip-interface-ports>`.

For :ref:`Proxy Printer <ch-intro-concepts-proxyprinter>` access the
standard IPP port ``631`` of local CUPS is used.

For :ref:`IPP Everywhere and AirPrint <ch-printer-ipp-everywhere>` UDP port ``5353`` is used.

Depending on the :ref:`Mail <ch-webapp-admin-options-mail>` settings
common SMTP ports are ``25``, ``465`` and ``587``.

Common IMAP ports used for |RST_LINK_MAILPRINT| are ``143`` and ``993``.

The :ref:`Secure JMX Connection <ch-security-jmx>` uses port ``8639``.

Many GNU/Linux distributions have strict default firewall policies, so
take some time now to ensure that these ports are open. Consult your
distribution documentation for details on how to open firewall TCP and
UDP ports.
